--Struggling to see how the word, "hypocrisy" would apply, given the fact that it is, by definition, a violation of one's own standards and has nothing to do with the perceptions of others.
Was St. Paul hypocritical in stating (In a nutshell) that if an idol was nothing, than the idol sacrifice couldn't possibly be defiled by it?
I would say, "no." He didn't belief in the gods represented by the idols and therefore the customs held no significance beyond the mundane as far as he was concerned.
