In the Orthodox Church, the last Sunday before Great Lent – the day on which, at Vespers, Lent is liturgically announced and inaugurated – is called Forgiveness Sunday. On the morning of that Sunday, at the Divine Liturgy, we hear the words of Christ:
In vain do you rejoice in no eating, O soul!
For you abstain from food,
But from passions you are not purified.
If you persevere in sin, you will perform a useless fast.
