What is the role of Argument and Evidence with Christian Faith?
It’s the Holy Spirit who gives us the ultimate assurance of Christianity’s truth. Therefore, the only role left for argument and evidence to play is a subsidiary role.
A Danger
Now there is a danger in all this so far. Some persons might say that we should never seek to defend the faith. Just preach the gospel and let the Holy Spirit work! But this attitude is unbalanced and unscriptural, as we shall see in a moment. For now, let us just note in passing that as long as reason is a minister of the Christian faith, Christians should employ it.
An Objection
Some people disagree with what I’ve said about the role of argument and evidence. They would say that reason can be used in a magisterial role, at least by the unbeliever. They ask how else we could determine which is true, the Bible, the Koran, or the Baghavad-Gita, unless we use argument and evidence to judge them? Now I’ve already answered that question: The Holy Spirit teaches us directly which teaching is really from God. But let me suggest two other reasons I think those who support the magisterial role of reason are wrong.
First, such a role would consign most believers to irrationality. The vast majority of the human race have neither the time, training, nor resources to develop a full-blown Christian apologetic as the basis of their faith. Even the proponents of the magisterial use of reason at one time in the course of their education presumably lacked such an apologetic.
I think Martin Luther correctly distinguished between what he called the magisterial and ministerial uses of reason.
The magisterial use of reason occurs when reason stands over and above the gospel like a magistrate and judges it on the basis of argument and evidence.
The ministerial use of reason occurs when reason submits to and serves the gospel. Only the ministerial use of reason can be allowed. Philosophy is rightly the handmaid of theology.
Reason is a tool to help us better understand and defend our faith; as Anselm put it, ours is a faith that seeks understanding. A person who knows Christianity is true on the basis of the witness of the Spirit may also have a sound apologetic which reinforces or confirms for him the Spirit’s witness, but it does not serve as the basis of his belief. Should a conflict arise between the witness of the Holy Spirit to the fundamental truth of the Christian faith and beliefs based on argument and evidence, then it is the former which must take precedence over the latter, not vice versa.

According to the magisterial role of reason, these persons should not have believed in Christ until they finished their apologetic. Otherwise, they would be believing for insufficient reasons. I once asked a fellow Bible College student, “How do you know Christianity is true?” He replied, “I really don’t know.” Does that mean he should give up Christianity until he finds rational arguments to ground his faith? Of course not! He knew Christianity was true because he knew Jesus, regardless of rational arguments. The fact is that we can know the truth whether we have rational arguments or not.
Second, if the magisterial role of reason were valid, then a person who had been given poor arguments for Christianity would have a just excuse before God for not believing in him.

Suppose someone had been told to believe in God because of an invalid argument. Could he stand before God on the judgment day and say, “God, those Christians only gave me a lousy argument for believing in you. That’s why I didn’t believe”? Of course not! The Bible says all men are without excuse. Even those who are given no good reason to believe and many persuasive reasons to disbelieve have no excuse, because the ultimate reason they do not believe is that they have deliberately rejected God’s Holy Spirit.
Therefore, the role of rational argumentation in knowing Christianity to be true is the role of a servant. A person knows Christianity is true because the Holy Spirit tells him it is true, and while argument and evidence can be used to support this conclusion, they cannot legitimately overrule it.
