“There are three things, my brethren, by which faith stands firm, devotion remains constant, and virtue endures.
They are prayer, fasting and mercy. Prayer knocks at the door, fasting obtains, mercy receives.
Prayer, mercy and fasting: these three are one, and they give life to each other.
Therefore, let prayer, mercy and fasting be one single plea to God on our behalf, one speech in our defense, a threefold united prayer in our favor.” excerpt, Sermons of St. Peter Chrysologus
