Adopting Martin Luther's interpretation of the "communicatio idiomatum", Brenz argued that the attributes of the Divine Nature had been communicated to the humanity of Christ which thus was deified.  If deified, it was everywhere, ubiquitous, just as His divinity, and therefore really present in the Eucharist.  This teaching of Brenz was in partial agreement with the Catholic faith—as to the fact, but not as to the explanation.  His assertion that Christ's human nature had been deified, and that His body was in the Eucharist as it was elsewhere, contradicted Catholic teaching and was considered heretical.
