Don’t mean to annoy or hijack the topic…but ‘Jesus is God’ and ‘Jesus is Consecrated Bread’ arent the same thing. Jesus is God. That is his substance. Jesus in the Eucharist is God but merely has the appearance (species) of bread and wine.
Back on topic…Jesus was always the Son of God, the eternal Word expressing perfectly the infinite knowledge the Father has (and is)of his infinite perfections. “In the beginning was the Word” (John 1:1) comes even before “In the beginning [of time] God created the heavens and the earth” (Genesis 1:1) Wild, huh?
At the fullness of time in history, the Son took on a human nature to enter earth. Physically, he entered the world in the womb of the Virgin Mary by the power of the Holy Spirit. Thus Mary is the Mother of God. This is accounted in Luke, and echoed in the Church’s prayer, the Angelus: “and she conceived by the Holy Spirit.”
Not sure what else to add here…not a theology major…but I hope I added a little bit to the already excellent canon of replies.
Peace of Christ.
