When we understand God has made man a little lower than the angels, yet man will rule them, the role of God the Father to God the Son becomes amazingly interesting.
Jesus Christ, the head of the Church, is also fully human and fully God. When we pray to God, we pray to God the Father, through faith in Christ, who is our intercessor.
**Jesus Christ, the head of the Church, is also fully human and fully God.**
fully human without sin = Jesus Christ (who denied his own human will)
fully God = God the Father (in Christ, keeping him sinless, and giving him all power)
