nounhistorical Christian Church
The adoration of the host or the bread consecrated in the Eucharist.
Chiefly used with reference to the unacceptability to some Protestants of the Roman Catholic doctrine of transubstantiation (in the context of Christian theological dispute over the exact nature of the presence of Christ in the elements of the Eucharist).
Early 17th century; earliest use found in Martin Fotherby (c1560–1620), bishop of Salisbury. From post-classical Latin artolatria from ancient Greek ἀρτο-, combining form of ἄρτος bread + post-classical Latin -latria.
