John Maxentius of Antioch and Transubstantiation

Q. Did John Maxentius advocate the Roman dogma of transubstantiation?

John Maxentius, Priest of Antioch (c. 6th Century A.D.):

Ye are the body of Christ, and members in particular, but that bread also, which the whole Church partakes of in memory of the His Passion, is His body. (J. P. Minge, Patrologiæ Cursus Completus, [1865], Patrologiæ Græcæ, Tomus LXXXVI, Joannis Maxentii, Dialogi, Lib. II, Cap. XIII, Col. 145). Here Trans. (J. H. Treat, The Catholic Faith; Or, Doctrines of the Church of Rome Contrary to Scripture and the Teaching of the Primitive Church, [1888], p. 194). Here
