Fides Et Ratio

"Jesus brings God's commandments to fulfilment, particularly the commandment of love of neighbour, by interiorizing their demands and by bringing out their fullest meaning. Love of neighbour springs from a loving heart which, precisely because it loves, is ready to live out the loftiest challenges. Jesus shows that the commandments must not be understood as a minimum limit not to be gone beyond, but rather as a path involving a moral and spiritual journey towards perfection, at the heart of which is love (cf. Col 3:14)." - St. John Paul II (Splendor of Truth, 15)
