Theodorus, [2591] presbyter of the church at Antioch, a cautious investigator and clever of tongue, wrote against the Apollinarians and Anomians On the incarnation of the Lord, fifteen books containing as many as fifteen thousand verses, in which he showed by the clearest reasoning and by the testimony of Scripture that just as the Lord Jesus had a plenitude of deity, so he had a plenitude of humanity. He taught also that man consists only of two substances, soul and body and that sense and spirit are not different substances, but inherent inborn faculties of the soul through which it is inspired and has rationality and through which it makes the body capable of feeling. Moreover the fourteenth book of this work treats wholly of the uncreated and alone incorporeal and ruling nature of the holy Trinity and of the rationality of animals which he explains in a devotional spirit, on the authority of Holy Scriptures. In the fifteenth volume he confirms and fortifies the whole body of his work by citing the traditions of the fathers.
