the doctrine of the High Anglican Church that after the consecration of the Eucharist the substance of the body and blood of Christ coexists with the substance of the consecrated bread and wine
Consubstantiation is a theological doctrine that (like Transubstantiation) attempts to describe the nature of the Christian Eucharist in concrete metaphysical terms. It holds that during the sacrament, the fundamental "substance" of the body and blood of Christ are present alongside the substance of the bread and wine, which remain present.
