This edition of Mar Jacob of Sarug's (d. 521) homily on the Transfiguration emphasizes the unity of the Old and New Testament. Jacob focuses on the symbolism of the apostles Jesus brings with him. Moses, the head of prophecy, and John, the beauty of apostleship, come together and Elijah and Simon are joined so that the keys Peter received over creation might be ratified. The volume constitutes a fascicle of The Metrical Homilies of Mar Jacob of Sarug, which, when complete, will contain the original Syriac text of Jacob's surviving sermons, fully vocalized, alongside an annotated English translation.
