So what did our holy brethren have to say about slavery anyway? Many of them like to point out that their sects were among the first to abolish it. In some cases there is a tiny grain of truth in that.
However from biblical times right up until the 19th century abolitionists, slavery was regarded as just as natural (and,presumably,holy) an estate as marriage.
This is a list of historical quotes from the church fathers onwards showing how our righteous brethren ACTUALLY regarded treating people as subordinate property.
