"A new commandment I give unto you: That you love one another, as I have loved you, that you also love one another. By this shall all men know that you are my disciples, if you have love one for another."

" 25 And behold a certain lawyer stood up, tempting him, and saying, Master, what must I do to possess eternal life?
[21] "He rejoiced in the Holy Ghost": That is, according to his humanity he rejoiced in the Holy Ghost, and gave thanks to his eternal Father.
26 But he said to him: What is written in the law? how readest thou? 27 He answering, said: Thou shalt love the Lord thy God with thy whole heart, and with thy whole soul, and with all thy strength, and with all thy mind: and thy neighbour as thyself. 28 And he said to him: Thou hast answered right: this do, and thou shalt live. 29 But he willing to justify himself, said to Jesus: And who is my neighbour? 30 And Jesus answering, said: A certain man went down from Jerusalem to Jericho, and fell among robbers, who also stripped him, and having wounded him went away, leaving him half dead.
31 And it chanced, that a certain priest went down the same way: and seeing him, passed by. 32 In like manner also a Levite, when he was near the place and saw him, passed by. 33 But a certain Samaritan being on his journey, came near him; and seeing him, was moved with compassion. 34 And going up to him, bound up his wounds, pouring in oil and wine: and setting him upon his own beast, brought him to an inn, and took care of him. 35 And the next day he took out two pence, and gave to the host, and said: Take care of him; and whatsoever thou shalt spend over and above, I, at my return, will repay thee.
36 Which of these three, in thy opinion, was neighbour to him that fell among the robbers? 37 But he said: He that shewed mercy to him. And Jesus said to him: Go, and do thou in like manner."
1st Epistle of St Paul to the Corinthians
Charity is to be preferred before all gifts.
"1 If I speak with the tongues of men, and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. 2 And if I should have prophecy and should know all mysteries, and all knowledge, and if I should have all faith, so that I could remove mountains, and have not charity, I am nothing. 3 And if I should distribute all my goods to feed the poor, and if I should deliver my body to be burned, and have not charity, it profiteth me nothing. 4 Charity is patient, is kind: charity envieth not, dealeth not perversely; is not puffed up; 5 Is not ambitious, seeketh not her own, is not provoked to anger, thinketh no evil;
6 Rejoiceth not in iniquity, but rejoiceth with the truth; 7 Beareth all things, believeth all things, hopeth all things, endureth all things. 8 Charity never falleth away: whether prophecies shall be made void, or tongues shall cease, or knowledge shall be destroyed. 9 For we know in part, and we prophesy in part. 10 But when that which is perfect is come, that which is in part shall be done away.
11 When I was a child, I spoke as a child, I understood as a child, I thought as a child. But, when I became a man, I put away the things of a child. 12 We see now through a glass in a dark manner; but then face to face. Now I know in part; but then I shall know even as I am known. 13 And now there remain faith, hope, and charity, these three: but the greatest of these is charity."
" 34 But the Pharisees hearing that he had silenced the Sadducees, came together: 35 And one of them, a doctor of the law, asking him, tempting him:
36 Master, which is the greatest commandment in the law? 37 Jesus said to him: Thou shalt love the Lord thy God with thy whole heart, and with thy whole soul, and with thy whole mind. 38 This is the greatest and the first commandment. 39 And the second is like to this: Thou shalt love thy neighbour as thyself. 40 On these two commandments dependeth the whole law and the prophets."
