“Mary is not a deity. She is not a goddess.”
Nah, she’s just the mother of God, that’s all.
Big, BIG logical non sequitur. Mary was the host mother of Jesus' body, not His Personality, not His soul and spirit that preexisted the body given to Him by The Father:
"Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:" (Heb 10:5 AV).
(That, by the way, is the First Christmas Carol, IMO.)
Mary was not the mother of The Jehovah that entered into that body. He existed before The Beginning of time, dimensions, and matter. Mary's predecessors were made in Elohim's image, not vice versa.
God don't have a mother...
