On the hemispheric ceiling of the cupola Prof. Bucmaniuk painted a striking image of God the Father, in whose lines and expressions he tried to express the divine attributes of majesty, omnipotence and infinity. However, because of the severity of the facial expression, the painting inspired dread, and had to be toned down by the artist.

The serious and stately face of God the Father is meant to express His role as Ruler of the Universe; the high forehead – His thoughtfulness in the exercise of His Providence; the flame-like grey hair, eyebrows, moustache and beard – His all-embracing love; the eyes – His omniscience. The gaze of God seems to penetrate the most secret recesses of the human soul. His outstretched arms reveal His creative power as they cast the earth into the boundless space of the universe. This figure of God, some of whose facial features resemble those of Metropolitan Andrey Sheptytsky, is surrounded by angels.

In the drum, on which the cupula rests, below the windows are icons of four Old Testament prophets: Isaiah, Ezekiel, Jeremiah and Daniel; and four religious symbols: the phoenix, the pelican, a seven-branched candelabrum, and a ship at sea.
