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). Thus the commandment "You shall not murder"
becomes a call to an attentive love which protects and promotes the life of
one's neighbour.
