Luke is a secondary source, not a primary source, at least in part, but to those who wish to believe, he's still a source. Most people get their "history" from secondary sources rather than primary sources. Why should Christians have a different relationship with the Bible? If I may paraphrase the OP, 'Why do some Christians believe the gospels are primary sources?' Most people don't think much about the difference between primary and secondary sources. The difference only matters to serious scholars which most people are not.
IMO all christian texts are primary sources. But sources of what? Of their ways of thinking? Yes. Of their beliefs? Yes. Historical events? No.
