And all day long, both at the temple and in their homes,
they did not stop teaching and proclaiming the Christ, Jesus.
-- Acts 5:34-42
The name "Jesus" signifies that the very name of God is present in the person of his Son, made man for the universal and definitive redemption from sins. It is the divine name that alone brings salvation, and henceforth all can invoke his name, for Jesus united himself to all men through his Incarnation, so that "there is no other name under heaven given among men by which we must be saved."
