Christian theology
The "Baptism, Eucharist and Ministry" document of the World Council of Churches, attempting to present the common understanding of the Eucharist on the part of the generality of Christians, describes it as "essentially the sacrament of the gift which God makes to us in Christ through the power of the Holy Spirit", "Thanksgiving to the Father", "Anamnesis or Memorial of Christ", "the sacrament of the unique sacrifice of Christ, who ever lives to make intercession for us", "the sacrament of the body and blood of Christ, the sacrament of his real presence", "Invocation of the Spirit", "Communion of the Faithful", and "Meal of the Kingdom".Eschatology is the study of the end of things, whether the end of an individual life, the end of the age, or the end of the world. Broadly speaking, it is the study of the destiny of man as it is revealed in the Bible, which is the primary source for all Christian eschatology studies.
The word eschatology (pronounced "eskatology") is derived from two Greek words meaning "last" and "study" (ἔσχατος, last; and λογία, lit. discourse).
