[1] This doctrine, apparently patterned after Christ's Incarnation (God is made flesh in the Person of Jesus Christ),[2] is the assertion that "God is made bread" in the Eucharist.

This view is similar but not identical to the theory of consubstantiation associated with Lollardy.
It is considered a heresy by the Roman Catholic Church[3] and is also rejected by classical Lutheranism.
[4] Rupert of Deutz (d. 1129) and John of Paris (d. 1306) were believed to have taught this doctrine.
