12. What History Can - and Cannot - Tell Us: Conclusion

Studying Christian history has left me with both greater gratitude and greater humility.

There is extraordinary beauty in the history of the Church.

Across centuries, Christians have cared for the poor and sick, protected vulnerable people, translated Scripture, challenged injustice, forgiven enemies, created beauty, crossed cultures to serve others, and quietly followed Christ in ways history may never have recorded.

I believe much of that beauty reflects the light of God's kingdom breaking into a dark world.

But Christian history also demonstrates something equally important:

Christians are fallible.

Brilliant theologians have been wrong.

Major Christian institutions have been wrong.

Biblical interpretations accepted for centuries have later been reconsidered.

Christians have sometimes sincerely believed that Scripture justified things that most Christians today recognize as deeply contrary to the way of Christ.

That does not mean every traditional Christian doctrine is therefore false.

It does mean that Christian consensus cannot make a doctrine infallible.

The fact that Augustine believed something does not make it true.

The fact that Aquinas believed it does not make it true.

The fact that Catholics, Protestants, Orthodox Christians, or the majority of Christians across many centuries believed something does not make it true.

Christian consensus is evidence worth considering.

It is not revelation.

At the same time, history is not irrelevant.

The witness of Christians closest to the apostolic age carries particular historical significance.

Earlier does not automatically mean correct. A Christian writing in the second century could misunderstand Scripture just as someone writing in the fourth or twenty-first century could.

But proximity matters.

When a belief appears very early—and especially when it appears in multiple Christian communities—it becomes more difficult to dismiss that belief as a modern invention.

That is why the early Christian evidence concerning the Holy Spirit, universal salvation, and Jesus matters to me.

It does not prove my conclusions.

But it does show that some ideas now regarded as radically outside Christian orthodoxy have roots much closer to Christianity's beginnings than many Christians realize.

It also reminds us that what eventually became dominant is not necessarily identical to everything Christians believed at the beginning.

History can therefore help us ask better questions.

It can show us where Christian beliefs developed.

It can reveal forgotten alternatives.

It can expose assumptions that later became treated as unquestionable.

It can show us the terrible consequences theological ideas sometimes helped produce.

And it can remind us that Christians are capable of repentance, reform, and rediscovery.

But history cannot finally tell us what God revealed.

For that, we must return to Scripture.

Jesus warned religious people that tradition could make “void the word of God” (Mark 7:13).

The Bereans were praised because they received teaching eagerly while still examining the Scriptures to determine whether what they were being taught was true (Acts 17:11).

That is the posture I want to carry into everything that follows.

Respect history.

Learn from tradition.

Listen seriously to Christians who came before us.

Pay particular attention to witnesses closest to the beginning.

But do not confuse any of them with God.

God is the final authority.

And Scripture must remain the standard by which every Christian doctrine—including the doctrines examined throughout this website—is tested.

Christian history therefore does not make me afraid to reconsider inherited theology.

It makes me more willing to do so carefully.

The Church has been wrong before.

The Church has also been reformed before.

And Jesus' promise still stands:

“I will build my church; and the gates of hell shall not prevail against it.” (Matthew 16:18)

I believe one of the ways Christ continues to preserve his Church is by continually calling his people back to truth.

So I end this study of Christian history not with cynicism, but with hope.

We can learn.

We can repent.

We can reform.

We can return to Scripture.

And we can continue asking, with humility and courage:

What has God actually revealed in His Word?

May the Spirit guide us into all truth (John 16:13).
