Florus Magistor and Transubstantiation

Q. Did Florus Magistor advocate the Roman dogma of transubstantiation?

Florus Magistor, A Deacon of Lyons (c. 9th Century A.D.):

Truly that bread of the holy oblation is the body of Christ, not in matter, or visible species, but in virtue and spiritual power. For neither is Christ's body produced for us in the field, nor does His blood originate in a vineyard, or is it wrung out by a press. Simple wine flows from grapes, the consecration of the mystical prayer is added to it, the infusion of the divine virtue occurs to it: and thus, in a wonderful and ineffable manner, what is naturally bread and wine from an earthly shoot, is spiritually made the body of Christ, that is, the mystery of our life and salvation, in which we see one thing by the eyes of the body, another by the sight of faith: nor do we taste that only which we receive with the mouth, but what we believe with the mind. (J. P. Minge, Patrologiæ Cursus Completus, [1852], Patrologiæ Latinæ, Tomus CXIX, Flori Diaconi Lugdunensis, Opuscula Adversus Amalarium, I, § 9, Col. 77). 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. 243). Here

This, therefore, He commanded to be celebrated, this to be frequented, until He come in the end of the world, when will be the rest of the saints, no longer in a sacrament of hope, whereby at this time the Church is knit together, as long as that is drunk which flowed from the side of Christ, but now in the very perfection of eternal salvation, when the kingdom is delivered to God and the Father, so that in that clear contemplation of incommutable truth, we shall have no need of bodily mysteries. (J. P. Minge, Patrologiæ Cursus Completus, [1852], Patrologiæ Latinæ, Tomus CXIX, Flori Diaconi Lugdunensis, De Expositione Missæ, § 63, Col. 55). 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. 243). Here
