June 28 - Prayer to St. Irenaeus

O great teacher of the Catholic faith who served to set a foundation upon which she could grow in peace and in truth, in the Spirit of God, you who valiantly defended her against attacks of heresy and shed your blood in the battle – pray we shall find shepherds today to explicate the faith of the apostles as clearly and loyally as you have done, that none shall be led astray into false doctrine by whim and fancy, by pride and envy, but drink rather the pure milk of our Mother and of the one true God. To vision of the Father let us come by revelation of His only-begotten Son.
