True, Christianity does teach that Jesus was fully God but it also teaches that he was fully man. He had human flesh just like you and I. The Torah prohibits cannibalism.
True, Jesus has human flesh, and the Law prohibits cannibalism, but Christianity teaches us to consume his body, blood, soul and
divinity.
We are eating and drinking the body and blood of God. Sure, God became man, but the man, Jesus, is still God, even when we consume his body and blood.
As for the original post:
I find the practice of recognizing transubstantiation as perpetual throughout the entirety of the Mass is extremely beneficial. Here are some personal reflections:
When the unconsecrated host is located at the entrance of the Church, this is God in the person of the Son, as paralleled to Jesus preaching pre-resurrection.
Then when the unconsecrated host is offered during the offertory, this is God in the person of God made man (Son), as paralleled to Jesus being either taken to or not stood up for to the High Priests or to the Roman Authority.
When the church priest declares the host to be his body and blood, the priest is God in the person of the Son, and the host is God in the person of the Father, as paralleled to the Son is the medium through which the Father speaks or as paralleled to the Son is the Word of God.
When the unconsecrated host is consecrated through the breaking of the body, pouring of the blood, and Holy Communion, this is God in the person of the Holy Spirit, as paralleled to Jesus giving his life for the life of others or as paralleled to the only begotten Son of God becoming man so that we might become God.
After another person receives communion with the consecrated host and goes in peace to love and serve the Lord, this is God in the person of the Holy Spirit as paralleled to the person’s spirit has been made holy through communion with God’s Spirit.
Thanks for sharing the interesting points and questions! I look forward to further discussion!
