What is the annual Church cycle?

This cycle, in fact, subsumes all the days of the year. We celebrate the major and minor feasts of the Lord, the feasts of the Theotokos, the feasts of saints, the commemorations of the consecration of churches, and the annual fasts. Through all of this, we repeat in our depths the words St. Athanasius records in one of his Paschal letters: “‘Our Passover, Christ, is sacrificed’ (1 Cor. 5:7). Henceforth the feast of the Passover is ours.”⁶¹⁸
