Marcus of Nitra and Transubstantiation

Q. Did Marcus Monk of Nitra advocate the Roman dogma of transubstantiation?

Marcus, Monk of Nitra (c. 4th Century A.D.):

Then Melchisedec brought out bread and wine for the refreshment of those who returned from the war. So also, Christ, the great High-Priest, gives sanctified bread and wine to those returning to him from the spiritual war, saying: Take, eat ye all of it. (J. P. Minge, Patrologiæ Cursus Completus, [1864], Patrologiæ Græcæ, Tomus LXV, S. Marci Eremitæ, De Melchisedech, Opusculum X, Caput. VIII, Col. 1132). 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], pp. 180-181). Here

Do not therefore, call types the truth.

But where the thing itself is present, it is not called a type, but the truth.
