- March 17 – Forgiveness Sunday
“For if ye forgive men their trespasses, your Heavenly Father will also forgive you; But if ye forgive not men their trespasses, neither will your Father forgive your trespasses (Matt. 6:14–15). What a simple and handy means of salvation! Your trespasses are forgiven under the condition that you forgive the trespasses of your neighbor against you. This means that you are in your own hands. Force yourself to pass from agitated feelings toward your brother to truly peaceful feelings—and that is all. Forgiveness day—what a great heavenly day of God this is! If all of us used it as we ought, this day would make Christian societies into heavenly societies, and the earth would merge with heaven.” (St. Theophan the Recluse).
