I appeal to you, Lord, God of Abraham, God of Isaac, God of Jacob and Israel, You the Father of our Lord Jesus Christ. Infinitely merciful as You are, it is Your will that we should learn to know You. You made heaven and earth, You rule supreme over all that is. You are the true, the only God; there is no other god above You.
Through our Lord Jesus Christ…and the gifts of the Holy Spirit, grant that all who read what I have written here may know You, because You alone are God; let them draw strength from You; keep them from all teaching that is heretical, irreligious or godless.
By Irenaeus of Lyon, 2nd century theologian and Bishop of Lyon
