Too much of what is written in the Gospels (e.g. miracles, alleged history) is implausible and can't be rationally accepted as objective truths. To try and defend them, detracts from the impression others would have of the person and other parts of the Christian message. I personally would consider them at the very least unaware of several facts, and I don't find any pragmatic value in error.
But if I saw a person, who simply lived what I Iike to consider the core Christian faith (that the divine operated through one man's way of life, and that it can be similarly propagated through others by their way of life), I wouldn't need an explanation to be moved to accept that message as valuable.I'd have a tangible experience of the most valuable part of the whole faith. Who knows it might even move this cold agnostic antisocial prick to act accordingly....now and again ;)
