“We duly proceed, my brethren, from feasts to feasts, duly from prayers to prayers, we advance from fasts to fasts, and join holy days to holy days…For the grace of the feast is not limited to one time, nor does its splendid brilliancy decline, but it is always near, enlightening the minds of those who earnestly desire it. For therein is constant virtue for those who are illuminated in their minds and meditate on the divine Scriptures day and night, like the man to whom a blessing is given, as it is written in the sacred Psalms”

(St. Athanasius the Apostolic, Festal Letter 5.1).
