I've been reading about the post-resurrection appearances of Christ, and the description of the earliest written records and development of the early Christian resurrection narrative is quite intriguing. It seems to show that there was a significant change of the meaning of resurrection beginning in the very first few decades of Christianity, between the time of Paul and when the gospels were written.
This weekend I had the fortunate opportunity to go to Fairfax, Virginia, to attend a seminar hosted by the Shalem Institute, an organization that fosters contemplative living and leadership. Their invited guest to present for their annual Gerald May Seminar was Bernard McGinn, who is Professor Emeritus of Historical Theology and of the History of Christianity in the Divinity School at the University of Chicago. McGinn is an American Roman Catholic Theologian and is considered one of the world's foremost expert scholars on the history of Christian mysticism. He has written seven volumes outlining the history of Christian mysticism, and may write two more, bringing the history up to the present time. This series is known as The Presence of God.
Religious texts are most often not literal history. They are allegory, narrative, parable, metaphor, simile, symbol, poetry, story, visionary, and figurative. They are not relating precise word-for-word conversations of the past, nor are they detailing literal events that took place. Yes, the Bible talks about many people and places that may have really existed, and may even abstractly refer to events that really took place, but it is not a history book.
