Perhaps GSC is making the assertion that, since the Holy Spirit came over Mary, that angels can do the same with any woman.
I wonder if he will figure out what it wrong with it before it has to be pointed out to him.
The Holy Spirit coming over Mary has nothing to do with sex. He did not have sex with Mary. Furthermore, the Holy Spirit is not an angel. Angels were created by God. The Holy Spirit is eternal.
Angels cannot have sex with anyone, nor can the Holy Spirit, for they are spirits. Furthermore, Jesus said that angels don’t marry (Matt. 22:30; Mark 12:25; Luke 20:35,36). If angels can’t marry, they can’t have children.
