“We believe that the Word became flesh and that we receive his flesh in the Lord’s Supper. How then can we fail to believe that he really dwells within us? When he became man, he actually clothed himself in our flesh, uniting it to himself for ever. In the sacrament of his body, he actually gives us his own flesh, which he has united to his divinity. This is why we are all one, because the Father is in Christ, and Christ is in us. He is in us through his flesh and we are in him. With him we form a unity which is in God.” (St. Hilary, Bishop of Poitiers, d. 368).
