There is only one God, the Lord Jesus Christ, but he has the ability to take on many forms and personas. When, in the Bible, Jesus speaks about the Father, he is speaking about his inner self — his soul — and when he speaks about the Holy Ghost, he is speaking about the effect of his actions and energy which radiate out into the universe, all of which are him, but simply different aspects of the same person.

Although it’s obvious they still love each other, Mary is no longer Jesus’ mother. She was his physical mother who birthed him while he was on earth, but his physical body was progressively transformed and glorified, made one with the Father of Heaven, so that it’s no longer the case that she is his mother.
