The presence of Christ

Only by severely downgrading or eliminating altogether the importance of initiation into the life of the Church can one speak of Orthodox witness to the heterodox in the framework of ecumenical encounter. Ultimately, this translates into denying the existential reality of the Church itself (the life in Christ), and hence, by extension, the very diachronic presence of the Incarnate Christ Himself.
