41 Hence, since there can be no doubt that Jesus Christ received a true body and had all the affections proper to the same, among which love surpassed all the rest, it is likewise beyond doubt that He was endowed with a physical heart like ours; for without this noblest part of the body the ordinary emotions of human life are impossible. Therefore the Heart of Jesus Christ, hypostatically united to the divine Person of the Word, certainly beat with love and with the other emotions- but these, joined to a human will full of divine charity and to the infinite love itself which the Son shares with the Father and the Holy Spirit, were in such complete unity and agreement that never among these three loves was there any contradiction of or disharmony.(40)
