So far a commentaries are concerned you can't ask for a better understanding of how this author read the text.
"Paul also, who learned by revelation from the Father concerning the Son, and says, 'When God Who separated me from my mother's womb and called me by His grace, was pleased to reveal His Son by my means.' This Paul has truly taught you who Jesus Christ is when he cries and says, 'Of whom is Christ in the flesh, Who is God over all, blessed for ever.' What occasion of calumny does not the word of Peter and Paul drive away from those who love calumny! for he called Him 'Christ' to show that He truly became man ; he said of Him, 'Who is of the Jews in the flesh,' to show that His existence does not date only from the time when He became incarnate; he said of Him, 'He is,' to tell us by his mode of expression that He is without beginning; he said of Him, 'Who is over all,' to proclaim Him Lord of created things; he said of Him, 'Who is God,' that we should not be drawn aside by the outward appearance and sufferings so as to deny his incorruptible Nature; he said of Him, 'blessed,' that we should worship Him as the Ruler of all, and not regard Him as a fellow-slave; he said of Him, 'Who is for ever,' to show that it is He Who by His word created all things, visible and invisible, whereby His Godhead is glorified. We have, then, Christ Who is God over all, Whom we shall worship, and we shall say to the heretics, 'In whomsoever the Spirit of Christ is not, he is none of His.' For we have the mind of Christ, and therefore we look for the revelation of God our Saviour, the Lord Jesus Christ," (The Syriac Chronicle, 2.5)
