Usually, those individuals who do believe in such myths place their priority on what they want to believe rather than what an individual actually said. More often than not, their minds are already made up and when presented with evidence counter to their claim (see my discourse with Jainārāyaṇ here) assert that such a claim (e.g. that of Jesus claiming divinity) was merely a falsehood devised by Paul or the "OHC&A" Church. Some of these myths (particularly the first one) are very common among new-age/universalist circles.
