The easiest way to define Christian philosophy is to say that Christian philosophy has two main presuppositions.
First, unlike most philosophies, Christian philosophy presupposes a theistic worldview. In other words, Christian philosophy starts with God. This theistic worldview though does not make it distinctively Christian, as other religious philosophies would share this assumption.
Second, Christian philosophy differs from other religious philosophy in that they presuppose a Christian God (trinitarian God) who is the God of the Old and New Testaments.
From a historical point of view, perhaps the greatest Christian philosopher has been Thomas Aquinas. He believed that through reason he could prove the truthfulness of a Christian God. In more modern times, Christian philosophers are called apologists.
Well there are many of them I know, but one is actually my favorite it has to do with what we hardly even realize.
If I bear witness of myself, my witness is not true. there is another that bareth witness of me, and I know that the witness of me is true. (john:5:31-32)
So this talks of the most controversial sentence in the New Testament. Though I look at it as a sentence of hope. The catholic church believed that if you didn't have a witness of what you did you where a liar unless you are capable of surviving torture. Though this verse was used by the catholic church as means of what atheists tend to use alot "saying this verse is contradictory" that is not true "at all" this verse in fact from the book of John has over five linear meanings, only one two could be accepted and if your a Christian like me you can understand it:
1) These are Jesus' spoken words: Jesus had a witness that he died and rose from the dead. John is the said to have been the closest to Jesus and even Baptized Jesus and was therefore was a witness to his life.
2) This was a matter of faith:Jesus witness was therefore close to him as it is written first person so he declares that he wasn't the witness, but Jesus mentions truth is the key to believe in what true.
The philosophy that you must be a validated witness telling the truth and have a specific reason kinda like Ancient Forensics in a way is even a Christian Principle. Honesty was a huge part of early Christianity. Today we live in an era where honesty is quite forgotten. This is a Christianity Philosophy thats one of the ten commandments even:
Don't bear false witness against thy neighbor. Maybe It was a matter of faith or a words spoken by Jesus in his belief of retelling the most difficult commandment to therefore obey. Thanks for reading.
