In a neat paragraph:
“In the Eucharist God wanted to donate us His love, which pushed him to offer his life for us on the cross. In the last supper, by washing the feet of his disciples, Jesus left us his commandment of love: ‘As I have loved you, so you also should love one another” (Jn 13,34). But for this to be possible we must remain united in him as branches on a vine (Jn 15,1-8), just as He himself chose to remain with us in the Eucharist so that we con remain in Him. Thus when we eat of His body and drink of His blood in faith, His love passes to us and makes us capable in turn of giving our lives for our brothers. (Jn 3,16). This is where Christian joy, Christian love is born”.
