At the highest point of the dome-like ceiling there is the monumental icon of Christ – Pantocrator (upholder of all creation). He is the apocalyptic Alpha and Omega. Also, high above the place where the faithful receive communion hangs the icon of the Rublev Old Testament Trinity, representing the moment when the Holy Trinity decided through the incarnation of the Second Person to begin the salvation of the human race.
At the back of the sanctuary is the mystical communion of the apostles: Christ nourishing his Church with his eucharistic body and blood. This scene is filled out on either side by the great fathers of the Church.
The back wall is dedicated to the final things: the dread judgment and heaven and hell.
