“Eschatology” is the name given to the understanding by religion of the ultimate destiny of the world and of man, the doctrine of the so-called “last things.” Everyone agrees that the early Church was eschatological par excellance. Her whole faith, her whole life, was shaped by her joyful and confident expectation of Christ’s return in glory, her anticipation of the common resurrection, and the consummation of all things in God. “Come, Lord Jesus: Maranatha!” This is the ultimate expression of her faith and worship in the liturgy, in prayer. This eschatology can be termed “cosmic,” for it is distinct, as such, from the individual or personal one.
To put it differently, and in somewhat over simplified terms, eschatology’s interest lies not in what happens to me when I come to the end of my life and die; rather, it is concerned with what will happen to the entire creation when Christ returns in glory and, according to Saint Paul, “All things shall be subjected unto him, and he himself be subject unto him that put all things under him, that God may be all in all” (1 Cor 15:28). (Fr. Alexander Schmemann, The Liturgy of Death, 120-121)
