This is the complete liturgy which begins with the procession about 5 minutes into the video. The Eastern Rite Chant of the Ukrainian Church is marvelous! Please note the altar as it is vested for this liturgy and that the Holy Father celebrates the Liturgy with his back to the nave, which is quite interesting too, since the Basilica when the Bishop of Rome celebrates Mass facing the nave is ad orientem toward the actual geographical east! Many thanks to Fr. G for sending this link!
