Ignorant Heresies
There are many “orthodox” preachers today whose study of Scripture has been so limited to what it says about soteriology that they could not protect the fold of God against heresies on the person of Christ. Ofttimes they themselves even entertain definitely heretical notions on the person of Christ, though perfectly unaware of the fact.
