From this passage Harvey infers that Irenæus held the procession of the Holy Spirit from the Father and the Son,—a doctrine denied by the Oriental Church in after times. [Here is nothing about the “procession:” only the “mission” of the Spirit is here concerned. And the Easterns object to the double procession itself only in so far as any one means thereby to deny “quod solus Pater est divinarum personarum, Principium et Fons,”—ρίζα καὶ πηγὴ. See Procopowicz, De Processione, Gothæ, 1772 ].
