— Mark Twain
"In all the ages the Roman Church has owned slaves, bought and sold slaves, authorized and encouraged her children to trade in them. Long after some Christian peoples had freed their slaves the Church still held on to hers. If any could know, to absolute certainty, that all this was right, and according to God’s will and desire, surely it was she, since she was God’s specially appointed representative in the earth and sole authorized and infallible expounder of his Bible. There were the texts; there was no mistaking their meaning; she was right, she was doing in this thing what the Bible had mapped out for her to do. So unassailable was her position that in all the centuries she had no word to say against human slavery. Yet now at last, in our immediate day, we hear a Pope saying slave trading is wrong, and we see him sending an expedition to Africa to stop it. The texts remain: it is the practice that has changed. Why? Because the world has corrected the Bible. The Church never corrects it; and also never fails to drop in at the tail of the procession — and take the credit of the correction. As she will presently do in this instance."
