Commentary on 1 John

Leo the Great (400–461)

It is pride to presume that it is easy not to sin, since the presumption itself is sin.

Our hope of eternal life is in him. He is the pattern of our patience. Otherwise we are using the likeness of a false profession if we do not follow the commands of him in whose name we glory. And these would not be burdensome to us and would free us from all dangers, if we would love only what he commands us to love.

The apostles had to ensure that no other truth would creep in and that no other doctrine would be taught. To do this, it was necessary to increase the capacity of those who were being taught and to multiply the constancy of that love which drives out all fear, not dreading the rage of persecutors.

This means the Spirit of sanctification, the blood of redemption and the water of baptism, which three are one and remain distinct, and none of them is separated from union with the others. This is the faith by which the church lives and moves.
