When Deeper Study Shakes Your Faith

The confusion is not your enemy

I know two people.

The first is someone who loves reading theology and apologetics. He spent hours listening to podcasts, watching doctrinal debates online, and trying to grasp all the intellectual arguments inside out. Yet, in the end, he chose to walk away from it all.

The second dug just as deep. But the deeper he went, the more the ground gave way beneath him. One night, the weight of it became so heavy that he stood close to an edge I don't want to name here.

Neither of them is shallow. They take their faith more seriously than most of us do. And it was that very seriousness that pushed them to the edge. Here is the thing no one warns you about: the deeper you understand, the easier it is for everything to wobble.

I'm writing this because I've stood on that shaky ground myself, never quite at the edge, but close enough to know what it feels like when a floor you trusted goes soft under you.

There's a term for it: deconstruction. It's the moment you step out of the tidy, black-and-white faith you inherited from your family or church, and start prying up the bricks to look at them yourself for the first time. It feels like the floor is dropping out. But James Fowler, who spent decades studying this, reached a conclusion that flips our fears on their head: he says it's a sign faith is growing up, not dying: the necessary move from a borrowed faith to one that's finally your own.

Most of the time, that shaking is just faith shedding its skin to grow. It isn't the sound of it breaking.

Tim Keller put it bluntly: “A faith without some doubts is like a human body without any antibodies in it.” Someone who's never wrestled with hard questions probably isn't stronger in faith than the rest of us. They just haven't needed the antibodies yet.

So before going any further, here's the first thing worth saying: your confusion is not your enemy. You're not asking too many questions. Nobody ever handed you a map to show where those questions actually belong, that's all.

Why more knowledge makes you wobble

Picture being handed a map where every landmark is drawn the exact same size. The timing of the end times, how to baptize, the mystery of the Trinity, or whether you can drink wine—all in the same font. When every doctrine looks equally important, just finding out that Christians disagree on one detail is enough to make your entire foundation shake. If they're wrong about the Sabbath, maybe they're wrong about the resurrection, too?

That's the trap. The way out isn't reading less. It's getting a better map.

In 2004, a theologian named Albert Mohler borrowed a concept from the ER: triage. When a dozen patients rush in at once, the nurses have to sort them. Which injury is life-threatening, which can wait, and which is just a scratch? Skip the sorting, and either everyone gets treated the same (and the critical patients die), or everyone is treated as critical (and the whole place shuts down in panic). Mohler argued that our faith needs the same sorting. In 2020, Gavin Ortlund wrote a book dedicated to this: Finding the Right Hills to Die On.

The core idea is simple, but it pulls people back from the edge: doctrines do not all carry the same weight. There are core beliefs that, if abandoned, mean you're no longer a Christian. There are secondary beliefs that draw lines between denominations without touching salvation. And there are gray areas that Scripture deliberately leaves to each person's conscience.

Filter your beliefs through these three tiers, and something strange happens: the confusion shrinks. You realize that most of the debates that used to keep you up at night aren't touching the foundation of the house at all. They're just arguments on the second and third floors. The foundation is still standing.

The bedrock we all stand on

Before we get to what sets us apart, let's stop for a second on something anxious people rarely notice: the common ground is staggering.

Think about it: Roman Catholicism, Eastern Orthodoxy, and Protestantism—three branches split by the most bitter schisms in history—still recite the very same confession: the Nicene Creed (settled in 325 and 381). All three confess one triune God. All three believe Jesus is “true God from true God,” of one being with the Father, truly made man, crucified, dead, and bodily resurrected “in accordance with the Scriptures.” And all three are waiting for his return.

At the core tier—the one that decides who is a Christian—these three traditions do not contradict each other. They agree. Which means that if you're standing on the Nicene Creed, whichever tradition you lean toward, you're standing on the same rock as billions of believers across twenty centuries. You are not lost.

The table below shows that shared ground (in green), and only then the real differences, sorted by tier.

The real differences, and the question underneath them all

I won't pretend the differences are just misunderstandings. They are real, and some run deep. But look closely and you'll see that nearly every Tier-2 clash flows back to one root question: when the sides disagree, who has the final say?

Catholicism answers: It's Scripture together with Sacred Tradition, interpreted by the Magisterium (the pope and the bishops). Orthodoxy answers: It's Scripture held inside Holy Tradition, guaranteed by the seven ecumenical councils. Protestantism answers with sola scriptura: Scripture alone as the final, unerring rule.

I’m no theologian, and I'm certainly not a pastor. I’m just a Christian who has wrestled with these exact questions himself. But I'll tell you straight what I believe, because honesty is its own kind of respect. I believe the Reformation’s answer is the most faithful to Scripture. Sola scriptura, properly understood, doesn't mean “only the Bible, throw out all tradition” (that's solo scriptura, a distortion). It means Scripture is the measuring stick that measures every other stick, and is itself measured by none. Popes, councils, and pastors can all be wrong, and all must be weighed against the Word. Paul praises the Bereans precisely because they “examined the Scriptures daily” to test even an apostle’s preaching (Acts 17:11).

"All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work."

— 2 Timothy 3:16-17

But honesty also makes me lay out the other side's strongest objections, and they really are strong:

One, the canon. It was the church that recognized the list of 27 New Testament books (first listed in full by Athanasius in 367, ratified at Hippo in 393 and Carthage in 397). If the church decided what is Scripture, how can Scripture stand over the church?

Two, tradition. Paul writes: “Stand firm and hold to the traditions that you were taught by us, either by our spoken word or by our letter” (2 Thessalonians 2:15), putting oral tradition right alongside written letters.

Three, justification. The one verse in the whole Bible that uses the phrase “faith alone” says the opposite: “a person is justified by works and not by faith alone” (James 2:24).

Four, the sacraments. Both Catholics and Orthodox argue that sacraments (such as baptism, the Eucharist, and confession) cannot be relegated to Tier 2. For them, these are necessary and essential means of salvation, forming an inseparable core of the life of faith.

An honest seeker has to stop right here and answer instead of dodging. The Reformation's reply, in short, is this: The church recognized the canon, it didn't create it (just as an astronomer finds a star rather than creating it). Sola scriptura doesn't throw out tradition; it sets it underneath, in service of the Word. As for James, R.C. Sproul put it simply: “the faith that justifies is never alone.” Paul is talking about the ground of justification (faith), James about its evidence (works). Luther, Calvin, and Knox would all nod along with James.

As for the fourth objection regarding the necessity of sacraments, the answer lies in the distinction between the essential core and the structural vehicle.

First, even within mainstream Roman Catholic theology, paragraph 1257 of the Catechism of the Catholic Church states: "God has bound salvation to the sacrament of Baptism, but he himself is not bound by his sacraments." This is why Catholic dogma recognizes the baptism of blood and the baptism of desire. The Eastern Orthodox Church shares a similar humility, often stating: "We know where the Church is, but we do not know where she is not." They confess the sacraments as the sure path established by Christ, yet they refuse to limit God's sovereign and free mercy outside of those rituals.

A Tier 1 belief must be absolute, applying to all people in all circumstances without exception, such as faith in the redeeming work of Christ. If sacraments can be waived or adapted in extraordinary circumstances (like a missionary in remote areas unable to perform rites, or a believer dying before baptism), then the physical ritual itself cannot be Tier 1. It is a Tier 2 vehicle conveying a Tier 1 reality. Furthermore, both Catholic and Orthodox traditions adapt their liturgies through inculturation and custom adjustments across different regions and centuries. Things that are adaptable and customizable belong to the superstructure, not the foundation.

The clearest biblical evidence for this is the penitent thief on the cross in Luke 23:39-43.

In the immediate context, Jesus is crucified between two criminals, representing two fundamental human responses to suffering and to Christ. The first mocks him, demanding immediate rescue. But the second thief experiences a moment of profound clarity. He rebukes the mocker, admitting that their punishment is just, while affirming Jesus' innocence. He then turns to Jesus with pure faith: "Jesus, remember me when you come into your kingdom."

Physically pinned to the cross, this dying man could not receive water baptism, partake in the Eucharist, or perform any religious deeds. Yet Jesus replies: "Truly, I say to you, today you will be with me in paradise." This declaration of salvation is absolute and carries no sacramental conditions.

The thief's salvation proves that while physical sacraments are the normative instruments (Tier 2) to lead us to God, the bedrock of salvation (Tier 1) remains the sovereign grace of God and the faith of the believer.

And here's something an anxious heart should know: the gap is narrower than we assume. In 1999, the Lutheran World Federation and the Catholic Church signed the Joint Declaration on the Doctrine of Justification, acknowledging a “consensus in basic truths.” The Methodists affirmed it in 2006, the Anglicans in 2016. Four centuries of theological war didn't erase the differences, but the differences were never as big as the shared core.

The differences are real. But underneath all of them lies a single question: who has the final say? Answer it, and what you're holding is a compass, not a whirlwind.

“But what about the Sabbath, and the glass of wine?”

Now for the very everyday fights, the ones that fray friendships and split small groups: keep the seventh-day Sabbath, or worship on Sunday? Can a Christian drink?

On the day of worship, there's a popular myth that the emperor Constantine “switched” worship to Sunday in 321. Not true. The earliest church was already gathering on “the Lord's Day” (the first day, the day Christ rose) very early on: the Didache (late first century), Ignatius's letter to the Magnesians (around 107), and Justin Martyr's detailed description (around 155) all come a century or more before Constantine. The 321 law gave that rest day civil force; it didn't invent it. Today the seventh-day (Saturday) folks, mainly Seventh-day Adventists, argue the fourth commandment is a creation-order command, permanent, never repealed.

On alcohol, Scripture both blesses moderate use (Psalm 104:15; Jesus's first miracle at Cana, John 2; the advice to Timothy to “use a little wine,” 1 Timothy 5:23) and condemns drunkenness (Ephesians 5:18; Proverbs 20:1; 23:29-35). One fact has to be said plainly: the wine of the Bible was real, fermented wine, not grape juice. Total abstinence is a product of the nineteenth-century temperance movement (Welch's grape juice was invented for it in 1869). It's an honorable choice, but not one you can turn into a law everyone has to keep.

What gets me is that Scripture saw both of these fights coming, word for word. In Romans 14, Paul names the two exact categories: days, and food and drink. He doesn't rule on who's right. He reframes both as matters of conscience, where sincere believers can land differently, as long as each acts out of honor to the Lord and doesn't trip up a brother.

"One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind."

— Romans 14:5

"Therefore let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath. These are a shadow of the things to come, but the substance belongs to Christ."

— Colossians 2:16-17

This is the very definition of adiaphora, “things indifferent,” neither forbidden nor required. This hill is not worth losing a brother over. Your conscience is free.

So in the end, which side is right?

This is the question you actually came here to ask, and I won't dodge it.

At Tier 1, the question dissolves. No side is “more right” than another about the Trinity, the deity of Christ, the resurrection, because all three confess it. So notice this: my friend who “knows it all and doesn't believe” isn't really rejecting a denomination. He's rejecting the shared core itself, and that's a different conversation, on a different tier, no longer a “which side is right” question at all.

At Tiers 2 and 3, though, there is a deciding question, and I already answered it: authority. As a Protestant Christian, I stand on Scripture as the final court, and on the gospel of grace (saved by grace through faith) as the hill worth dying on. I hold that with conviction, not contempt. Because my Catholic or Orthodox brother, if he's standing on the Nicene Creed and trusting Christ, is my brother, even as he and I go on arguing fiercely about plenty of things on the second floor.

What I just said isn't relativism, not "everyone's right in their own way, who can say." Triage is exactly what keeps you out of that ditch. It lets me say two things at once without contradiction. The core really is shared by all three. And on everything else, there are better and worse answers, and I believe I know where the better one is.

Four centuries ago, in the middle of the Thirty Years' War, with blood being spilled over religious difference, a Lutheran theologian named Rupertus Meldenius wrote the line that would become a compass for millions (people love to pin it on Augustine, but it's his, around 1627):

In essentials, unity; in non-essentials, liberty; in all things, charity.

That's the answer. Not “every side is right,” and not “only my camp is saved.” It's this: hold the core tightly, hold the edges loosely, and lay love over all of it.

To the one standing at the edge

Let me stop arguing for a moment, because maybe you didn't come here for a diagram. Maybe you came in the dark, like the second person I mentioned at the start, the one whose confusion drove him near an edge I won't name lightly. If that's you, please hear this slowly.

Doubt is not a verdict against you. Scripture is not embarrassed by doubters. When Thomas said he wouldn't believe until he touched the wounds, Jesus didn't scold him. He held out his hand. When John the Baptist, sitting in prison, sent word to ask “Are you the one who is to come?”, the Lord didn't shame his weak faith. He gave him evidence. There's even a psalm (Psalm 88) that goes from darkness to… darkness, ending on “darkness is my closest friend.” And God left it in the Bible anyway, as if to say that honest lament is also prayer.

"I believe; help my unbelief!"

— Mark 9:24

That might be the most honest prayer in all of Scripture: a man holding faith and weakness in the same breath, and Jesus answered him.

And hear this part clearly. If the despair has gotten so heavy that you've thought about ending your life, this isn't only a theology problem anymore. Don't carry it alone. Today, tell a safe person (a steady friend, a wise pastor) and a mental-health professional. The two aren't enemies; a wise carer of souls knows when to call the doctor.

As for what God makes of someone who didn't make it out of that darkness, Christian traditions don't all answer that question the same way, and this isn't the place for me to settle it on your behalf. What I do believe, and believe no tradition would deny, is this: God sees the full weight of the pain, the illness, the exhaustion behind a thought like that, more clearly than any of us ever could. He is not a judge sitting in wait for the moment to let go of your hand exactly when you need him most.

As for the fear that “I'm losing my faith,” the numbers tell a very different story than that fear does.

Read those numbers slowly. Your confusion isn't the end. For most people who walk through it, it's the doorway into a deeper, sturdier faith that this time is actually their own.

A compass, not a cage

I think we've misunderstood what doctrine is for.

We imagined it as a cage, a sealed system that hands us absolute certainty about everything, so that no question is allowed to stay alive. So when one bar of the cage cracks, we think the whole prison is collapsing, and we panic.

But doctrine is a compass, and it was never a cage. A compass doesn't answer every question about the terrain; it won't tell you about every stone on the path. It does one thing, and does it completely: it keeps you pointed north, even when the fog is so thick you can't see the way. For a Christian, that north is Christ.

The deep study that once shook you can become the very thing that roots you, if you hold the core tightly and the edges loosely. My friend who “knows it all” has every map but has let go of the compass. The one at the edge is still holding it, even with a shaking hand. If that's you, here's the last word: you don't have to know everything to be safe. You only have to know north, and keep walking.

You don't have to be right about everything to be held by Christ. You only have to be held by him.
