Why Do We Believe

Christians claim that the entire Bible, OT and NT are inspired books of God, and revelations from God. But we know the NT was not among the "holy scriptures" which Timothy had known from his youth the first one being written around AD45. 

At the beginning of his letter Luke told his friend:

Inasmuch as many have undertaken to compile a narrative of the things that have been accomplished among us, just as those who from the beginning were eyewitnesses and ministers of the word have delivered them to us, it seemed good to me also, having followed all things closely for some time past, to write an orderly account for you, most excellent Theophilus, that you may have certainty concerning the things you have been taught.

Luke wasn't inspired by God nor had he received any revelations from God. He writes for a man named Theophilus, so that he believes in these things. The Gospel of Luke is simply a work of collecting quotes and information from eye-witness accounts and written addressed to one man. Nothing inspired; nothing revealed from God to Luke; Luke is simply making an account of how things happened.

What Luke does is very similar to the folks who collected sayings of the prophet Muhammad from his companions and eye-witnesses, and also showed stories told by eye-witnesses. This is what Luke did; the only difference is that we do not call their work the word of God, like Christians do with the Gospel of Luke.

Why do we say the Gospel of Luke is the result of inspiration or revelation from God. 

Members of the Church of Christ have an attitude similar to the one Russian President Putin chastised Obama for having we believe ourselves to be exceptional. The Christian religion began on Pentecost and as evolution did has gone through a series of mutations. The Church of Christ today is the result of a group of Presbyterians upset with the status quo. We took first-century conveniences, personal preferences, and biases and our conveniences, personal preferences, and biases and made them law. Calling ourselves Church of Christ does not make us the church of Christ nor does calling one Christian make them Christian. We are just one of many groups that believe it has an inside track on truth.
