+Jn 15: 9-11
As the Father loves me, so I also love you. Remain in my love.
If you keep my commandments, you will remain in my love, just as I have kept my Father’s commandments and remain in his love.
“I have told you this so that my joy may be in you and your joy may be complete.
The New American Bible
The Catechism of the Catholic Church
1823 Jesus makes charity the new commandment. By loving his own “to the end,” he makes manifest the Father’s love which he receives. By loving one another, the disciples imitate the love of Jesus which they themselves receive. Whence Jesus says: “As the Father has loved me, so have I loved you; abide in my love.” And again: “This is my commandment, that you love one another as I have loved you.”
1824 Fruit of the Spirit and fullness of the Law, charity keeps the commandments of God and his Christ: “Abide in my love. If you keep my commandments, you will abide in my love.”
