"You were right when you wrote, "since Jesus was God incarnate" "she could be viewed as the Mother of God." Why not stop there?"
Because to do so would be imprecise. Mary is not the "mother" of God the Father not is she the "mother" of God the Holy Spirit.
"This illustrates the fact that most Protestant objects to veneration of Mary result from never really thinking the issues through."
Usual tired argument. "Your just not as smart as us."
Thank you, Petronius Nestorius Maximus.
Actually, your heresy is closer to that of the Tritheists than Nestorius, but the combination had such a nice ring to it. In any case, what you uttered denies the real unity of the Godhead. Watch your back, the Muslims despise tritheists.
