Ah alright, I'm not sure if the Greeks spoke of it as libertine but that's usually the philosophical concept, just as the Bible never uses certain terms yet we recognize them through theological names.
The whole of Calvins soteriology hinges on total inability. Those who accept that one tenet, which is based on a misread of Romans 5 that many can't see past, and then reading that back into other verses that has come to be to be the lynchpin. If it's accepted, all of the 5-points become both logically and Biblically necessary.
