What I wrote is common knowledge, so claiming I copied it from someone else only makes you look petty and peevish.

That some early popes were slaves is immaterial to the fact that Church tradition saw slavery as morally acceptable until the late 19th century. There were many popes who owned slaves. That, sir, is an indisputable fact. Since Marty said that the pope must follow tradition, Saint John Paul II was clearly wrong when he taught that slavery of any kind was intrinsically evil.

My point, which for some unknown reason, you are unable to grasp, is that Marty is, once again, showing his ignorance of Church history and practice.
