Isidore of Seville and Transubstantiation

Q. Did Isidore advocate the Roman dogma of transubstantiation?

Isidore, Archbishop of Seville (c. 560-636 A.D.):

'Thou art a priest forever according to the order of Melchisedec.' Namely, on account of the mystery of the Sacrament, which He commanded Christians to celebrate: that we should not offer victims from the flock according to Aaron, for a sacrifice, but an oblation of bread and wine; that is the Sacrament of His body and blood. (J. P. Minge, Patrologiæ Cursus Completus, [1862], Patrologiæ Latinæ, Tomus LXXXIII, S. Isidori Hispalensis Episcopi, Quæstiones In Vetus Testamentum, In Genesin, Cap. XI, § 5, Col. 240). 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. 186). Here

It is called a Sacrifice, as a sacred act: because by the mystical prayer it is consecrated in memory of the Lord's Passion for us: wherefore by His command we call this the body and blood of Christ, which, while it is of the fruits of the earth, is sanctified and becomes a Sacrament, the spirit of God working invisibly. The Sacrament of this bread and cup, the Greeks call the Eucharist. (J. P. Minge, Patrologiæ Cursus Completus, [1850], Patrologiæ Latinæ, Tomus LXXXII, S. Isidori Hispalensis Episcopi, Etymologiarum, Lib. VI, Cap. XIX, § 38, Col. 255). 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

For the bread which we break is the body of Christ, who says, I am the living bread, etc. But the wine is His blood, and this is what is written, I am the true vine. But bread, because it strengthens the body, is therefore called the body of Christ. And wine, because it creates blood in the flesh, is therefore referred to the blood of Christ. But these two things are visible: yet the things signified pass into the Sacrament of the divine body through the Holy Spirit. (J. P. Minge, Patrologiæ Cursus Completus, [1862], Patrologiæ Latinæ, Tomus LXXXIII, S. Isidori Hispalensis Episcopi, De ecclesiasticis officiis, Lib I, Cap. XVIII, Col. 755). 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. 195). Here
