Leo the Great

In his own words on 1 John

• 1 John 1:8

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

  SERMONS 41.1

• 1 John 2:6

  In Him therefore we find our Model of patience, in Whom we have our Hope of life eternal; for "if we suffer with Him, we shall also reign with Him," since, as the Apostle says, "he that saith he abideth in Christ ought himself also to walk as He walked." Otherwise we make a vain presence and show, if we follow not His steps, Whose name we glory in, and assuredly they would not be irksome to us, but would free us from all dangers, if we loved nothing but what He commanded us to love.

  SERMONS 90.2

• 1 John 4:18

  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.

  SERMONS 76.5

• 1 John 5:8

  "This is He that came by water and blood, Jesus Christ: not by water only, but by water and blood. And it is the Spirit that testifieth, because the Spirit is the truth, because there are three that bear witness, the Spirit, the water and the blood, and the three are one." The Spirit, that is, of sanctification, and the blood of redemption, and the water of baptism: because the three are one, and remain undivided, and none of them is separated from this connection; because the catholic Church lives and progresses by this faith, so that in Christ Jesus neither the manhood without the true Godhead nor the Godhead without the true manhood is believed in.
