Christianity was never “founded”.
Well, it certainly wasn't losted :-)
Seriously, to say that Christianity was "founded" is simply to denote a moment in time that splits what was before with what is afterward: beforehand the Messiah was a future hope for whom people waited, afterward He was a recognizable figure who could be specifically worshipped.
Despite the headline—which, to me, makes about as much sense as, "Are the words of Jesus more important than the rest of the New Testament?"—the article is actually pretty good, for apologetics. I'm sure the exercise was profitable for the writer.
Thanks for pinging me.
