From my recent paper ("St. Paul on Jesus Christ, 'Our Great God and Savior'"):
In Romans 9:5 St. Paul refers to Christ as "the Messiah, Who is over all, God blessed forever." All the Church Fathers who made use of this text in their Christological writings interpreted the original Greek, "ὁ ὢν ἐπὶ πάντων θεὸς," to mean that Christ is "God over all" (Drum). These witnesses include Sts. Irenaeus, "Cyprian, Athanasius, Gregory of Nyssa, Ambrose, Augustine, and Hilary" (ibid.) This syntax has, for the Fathers, the same meaning as the syntax of the alternative translation in the NRSV footnote: that our Lord is the "Messiah, Who is God over all, blessed forever" (1922c).
