In fact the widest consensus to date (and when we discount fundamentalist scholars, the overwhelming consensus to date) is that (a) the Gospels and Acts are substantially vexed by mythical and fabricated material, presenting any scholar with the challenging problem of ascertaining what in them is true and what false, or what if any truths about the origin of the religion can be inferred from them, and (b) the canonical Epistles are vague and fragmentary as to any details about how the religion actually began, and what data they do provide is open to endlessly debatable interpretation.
