The church also believes that the incarnation was necessary.
There has been a debate in the church as to whether the incarnation was necessary. The Church believes that the incarnation of Jesus was not dependent on the sin of man, but that such a stupendous event was planned from the beginning. The church believes that there is no difference in religion before the fall of man and after the fall of man. Consequently, since one of the duties of Christ is to act as Mediator between man and God, that office of mediator was necessary both before and after the fall of man, and therefore the coming of Christ to earth was planned from the beginning.
The church does not believe that the Word, that is the part of the triune God, changed His essential being by being incarnated. Jesus did not cease to be what he was before when He became incarnate. He merely took on an additional form without changing in any way His original nature.
The church believes that Jesus took His Human nature from his mother. There has been a belief in the Christian church that Jesus brought His body with him, and that Mary was only the channel or pipe through which this body passed. If this belief were correct, then Jesus was not of the same human stock as we, and there is no brotherly relation between us and Jesus. The church believes that Jesus took his bodily substance from Mary, His human mother, and was organically connected to the human race.
