4. Wherefore I do also call upon thee, Lord God of Abraham, and God of Isaac, and God of Jacob and Israel, who art the Father of our Lord Jesus Christ, the God who, through the abundance of Thy mercy, hast had a favour towards us, that we should know Thee, who hast made heaven and earth, who rulest over all, who art the only and the true God, above whom there is none other God; grant, by our Lord Jesus Christ, the governing power of the Holy Spirit; give to every reader of this book to know Thee, that Thou art God alone, to be strengthened in Thee, and to avoid every heretical, and godless, and impious doctrine.
