Despising the Mother of Jesus is an error of the protestant sects
Oh, I don't despise her. And, I am not in a "protestant sect". Its that if one would read the Bible (vs. listening to the RC traditions) one would find she was another sinner like the rest of us. She happen to be chosen to bear the physical body of Jesus, but needed a Savior just like I do. The veneration of her is a cult-like sickness borne of a man-centered worship...not reverence to the One who is worthy.
Characterizing protestants of "despising" Mary is an error. She is respected and loved by every Reformed church of which I'm aware. But she is not raised to the level a member of the Trinity. Protestants pray directly to the Persons of the Trinity, and not to intercessors.
