Jesus prays for us to love with divine love. "That they may all be one; even as thou, Father, art in me, and I in thee, that they also may be in us, so that the world may believe that thou hast sent me. The glory which thou hast given me I have given to them, that they may be one even as we are one, I in them and thou in me, that they may become perfectly one, so that the world may know that thou hast sent me and hast loved them even as thou hast loved me" John 17: 21-23

1 Peter 1:22-23
"You have been obedient to the truth and purified your souls until you can love like brothers, in sincerity; let your love for each other be real and from the heart – your new birth was not from any mortal seed but from the everlasting word of the living and eternal God."

Benedict XVI  Angelus, Jan 31, 2010
Love is the sign of Christians. It sums up their entire life: what they believe and what they do... (It is) the "style" of God and of believers, it is the behaviour of those who, in response to God's love, make their life a gift of themselves to God and to their neighbour. In Jesus Christ these two aspects form a perfect unity: he is Love incarnate. This Love has been fully revealed to us in Jesus Christ. Fixing our gaze on him, we can confess with the Apostle John: "We have come to know and to believe in the love God has for us" (cf. 1 Jn 4: 16; Encyclical Deus Caritas Est, n. 1).
