What is the benefit of the annual Church calendar?

There is a line from which we must not deviate, neither to the right nor to the left. The Savior clearly declared: “I am the way, the truth, and the life” (John 14:6), and He had previously warned His people in the Old Testament not to deviate from the way to the right or to the left (Deut. 5:32). In every celebration of a Church occasion, if the heart of the believer is not inflamed with love for God and for his brothers and sisters, and with longing for the heavenly life, his celebration cannot be considered as ecclesiastical, scriptural, spiritual, or acceptable to God.
