See what love the Father has bestowed on us that we may be called the children of God. Yet so we are. The reason the world does not know us is that it did not know him. Beloved, we are God’s children now; what we shall be has not yet been revealed. We do know that when it is revealed we shall be like him, for we shall see him as he is. (1 Jn 2:29-3:6)

As the ancient Fathers and Mothers of the Church used to say, “the Son of God became the Son of Man so that women and men could become the dear children of God.” The celebration of the Most Holy Name of Jesus reminds us what his name means: God saves.
