# Consecration ## Catechism of the Catholic Church The dedication of a thing or person to divine service by a prayer or blessing. The consecration at Mass is that part of the Eucharistic Prayer during which the Lord's words of institution of the Eucharist at the Last Supper are recited by the priestly minister, making Christ's Body and Blood--his sacrifice offered on the cross once for all--sacramentally present under the species of bread and wine ([[2.2.1.3.p40#^ccc-1352|1352]], [[2.2.1.3.p40#^ccc-1353|1353]]).
