Mark 12:31-33

New Revised Standard Version, Anglicised Catholic Edition

³¹ The second is this, “You shall love your neighbour as yourself.” There is no other commandment greater than these.’ ³² Then the scribe said to him, ‘You are right, Teacher; you have truly said that “he is one, and besides him there is no other”; ³³ and “to love him with all the heart, and with all the understanding, and with all the strength”, and “to love one’s neighbour as oneself”,—this is much more important than all whole burnt-offerings and sacrifices.’
