From the homily of His Holiness, Patriarch Bartholomew I at the conclusion of the Divine Liturgy in the Cathedral of Saint George in Istanbul:
Every celebration of the Divine Liturgy is a powerful and inspiring con-celebration of heaven and of history. Every Divine Liturgy is both an anamnesis of the past and an anticipation of the Kingdom. We are convinced that during this Divine Liturgy, we have once again been transferred spiritually in three directions: toward the kingdom of heaven where the angels celebrate; toward the celebration of the liturgy through the centuries; and toward the heavenly kingdom to come.
This overwhelming continuity with heaven as well as with history means that the Orthodox liturgy is the mystical experience and profound conviction that "Christ is and ever shall be in our midst!" For in Christ, there is a deep connection between past, present, and future. In this way, the liturgy is more than merely the recollection of Christ's words and acts. It is the realization of the very presence of Christ Himself, who has promised to be wherever two or three are gathered in His name.
