Jesus received flesh from the flesh of Mary. He walked here in that flesh, and he gave that flesh to us to be eaten for salvation [John 6:54-63]. No one eats that flesh without first worshiping. . . . [Jesus said] “Understand spiritually what I say. You are not to eat this body that you see nor drink the blood that those who crucify me will shed. I have presented a mystery to you. Spiritually understood, it will bring life. Although this must be celebrated visibly, it must be understood spiritually.”
