i really have to chuckle at your quoting john calvin.
as far as i know he didn’t claim to be infallible.
You’re missing the point. Probably deliberately.
Ah yes, the old "we never claimed to be infallible" defense.
Actually, this defense is nothing more than textbook moral relativism. Protestants have been employing this more and more frequently over the past few decades to condone female clergy and abortion and homosexuality, I shudder to imagine what they will embrace next.
