I do not intend to ask whether Christianity is “true” or “false,” or to establish, for example, the former hypothesis. Rather, what will be in question here is what Christianity considers as truth – what kind of truth it offers to people, what it endeavors to communicate to them, not as a theoretical and indifferent truth but as the essential truth that by some mysterious affinity is suitable for them, to the point that it alone is capable of assuring them salvation. We are trying to understand the form of truth that circumscribes the domain of Christianity, the milieu in which it spreads, the air that it breathes, one might say – because there are many sorts of truths, many ways of being true or false. And we are also perhaps trying to get away from the concept of truth that dominates modern thought and that, as much in and of itself as in its multiple implications, determines the world in which we live.

Presumably those who profess and call themselves Christians believe their religion to be in some sense true; but in what sense? ... The truth of the Christian faith is the truth of a faith, or a way of life which shows itself true ... for those who live it.

The way in which I know Christianity is true is first and foremost on the basis of the witness of the Holy Spirit in my heart. And this gives me a self-authenticating means of knowing Christianity is true wholly apart from the evidence. And therefore, even if in some historically contingent circumstances the evidence that I have available to me should turn against Christianity, I do not think that this controverts the witness of the Holy Spirit.

Christianity may be true or false, but it makes claims subversive of all the rationalist projections of life. It rests on presuppositions which cannot by any ingenuity be reconciled with any view which denies the miraculous, the unique, the individual. Its whole meaning comes from a faith in a life of spirits behind the veil. It cannot without hopeless error be confused with those systems which deny such a life or treat it as impersonal.

Christianity is more than history; it is also a system of truths. Every event which its history records, either is a truth, or suggests a truth, or expresses a truth which man needs to assent to or to put into practice.

Truth can never be merely a holy cluster of concepts, conditioning, or beliefs. It is not an event, nor is it an object apart from you in some sacred vault. For Truth to be Truth, it must be unchanging, immutable, ever present – yet it is beyond characteristics and conditions. It cannot be anything that comes and goes, for everything changeful arises from it and comes and goes in it.

…the truths of Christianity are constant, unchanging, and meant for all people, times, and places. But the methods by which truth is articulated and practiced must be culturally appropriated, and therefore constantly translated …if doctrine is constant and practice is constantly changing, the result is living orthodoxy.

But it isn’t a choice, because Jesus said, “I am the way, the truth, the life.” If you come across truth in any form, it isn’t outside your faith as a Christian. Your faith just got bigger. To be a Christian is to claim truth wherever you find it.

Truth is the agreement of our ideas with the ideas of God.

Christian theology was a revised version of Greek philosophy and the effort Plato and his heirs made to discern the permanent behind the sensible, the Ideal and the Real behind the world of individual things — ever in flux, becoming and decaying and never, ever reliably and completely True.

The paradox in Christian truth is invariably due to the fact that it is the truth that exists for God. The standard of measure and the end is superhuman; and there is only one relationship possible: faith.

The religious definition of truth is not that it is universal but that it is absolute.

"What is truth? Pilate was not alone in dismissing this question as unanswerable and irrelevant for his purposes. Today too, in political argument and in discussion of the foundations of law, it is generally experienced as disturbing. Yet if man lives without truth, life passes him by; ultimately he surrenders the field to whoever is the stronger. "Redemption" in the fullest sense can only consist in the truth becoming recognizable. And it becomes recognizable when God becomes recognizable. He becomes recognizable in Jesus Christ. In Christ, God entered the world and set up the criterion of truth in the midst of history. Truth is outwardly powerless in the world, just as Christ is powerless by the world's standards: he has no legions; he is crucified. Yet in his very powerlessness, he is powerful: only thus, again and again, does truth become power."

Truth is really whatever can be shown to correspond to reality. Truth is what the facts are essentially. Facts are after all points of data that you can verify to be accurate. A lot of people hate these definitions because it completely undermines their theology. They can’t make the assertions that they want to by saying anything is the absolute truth, because under the definition of either word no you don’t!
