Protestant critics of Orthodoxy fault us for many things, but one of the foremost of their objections is our devotion to Mary, the Mother of Jesus. Hostility to Roman Catholicism is built into Protestant DNA, so anything in Orthodoxy that resembles something in Roman Catholicism will be subject to criticism, including such more or less innocuous things like clergy wearing cassocks and calling themselves “Father”. Our Orthodox devotion to Mary (whom we call “the Theotokos”) often heads the list of Protestant objections, since it features so prominently in Roman Catholicism.
