The founding of the Church brought about the communion of God with man. The uncreated and eternal God was united ontologically with created and mortal man. Eternal life manifested itself in temporal life. Created and mortal man thus becomes through grace uncreated, eternal and everlasting, or, in other words, unoriginate, because the grace which regenerates his existence is uncreated, eternal and unoriginate. There is nothing left anymore to prevent the joining of created and uncreated, temporal and eternal, present life and life to come. The time of the realization of these events is 'last' time. The day and the hour are 'last.' Nothing else is awaited, neither Messiah, nor Paraclete, nor Antichrist. All things are present—Christ, and the Paraclete, and the Antichrist. Christ is present with the Holy Spirit in the Church, and the Antichrist is present too as an evil spirit that makes war on the Church. The presence of the Antichrist constitutes an eschatological phenomenon not so much in itself, as in relation to, or to be precise, in contrast with the eschatological presence of Christ. All those things which the incarnate manifestation of God in history have a share in bringing about (i.e., his Crucifixion and his Resurrection) create the last time, the last day, the last hour, which exists here and now.
The eschata, then, the last things, are not limited to the end of history, but exist already in the life of the Church. The last times encompass the whole period following the coming of Christ. And Christ who is "the Alpha and Omega...which is, and which was, and which is to come," is the Lord, the beginning and the end of history. Whoever has Christ, has life. The experience of this life already exists in the Church. The renewal and deification of man in Christ, which is awaited in the age to come, is already lived in this life: "Now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is."
Although it is revealed to the world "through a glass, darkly," the kingdom of God does not cease to be truly present.
