Mark 1:11

The Greek printed copies, and some manuscripts read with St. Matthew (iii. 17.) in whom, Greek: en o, thus St. John Chrysostom, Euthymius, and Theophylactus. Some few, however, have Greek: en soi, in thee, with the Syriac and Latin text. (Pastorini) --- All the Fathers cite these verses for a proof of the Trinity: the testimony of the Father speaking, of the Son receiving the testimony, of the Holy Ghost descending in the shape of a dove. (Pastorini in Matt. iii. 17)
