Ping!
Thinking of adult baptism as a sacrament and the Lord's Supper as "tasting the body and drinking the holy blood of our Lord Jesus Christ" are not Baptist beliefs. Also, the article indicates that they may have been adoptionist which contradicts an earlier reference that "they held to the orthodox view of the Trinity".
Clearly the Paulicians held the same belief as Baptists in that adult baptism after coming to faith was the ordinance they practiced and their pastors were not of an elevated rank. It really is such a shame so little dependable information can be found.
