The Christian Sacrament and Sacrifice (often published with Missale Romanum or The Depth and Mystery of the Roman Mass) is a 17th-century theological work by Daniel Brevint (1616–1695). Originally published in 1673, it is an influential Anglican treatise that explains the Holy Communion as both a sacrament of grace and a sacrifice of praise, providing a bridge in understanding between Protestant, Reformed, and Roman Catholic views of the Eucharist.
