Luke 17:3-10 (15th Saturday of Luke)
The Lord said, "Take heed to yourselves; if your brother sins, rebuke him, and if he repents, forgive him; and if he sins against you seven times in the day, and turns to you seven times, and says, 'I repent,' you must forgive him." The apostles said to the Lord, "Increase our faith!" And the Lord said, "If you had faith as a grain of mustard seed, you could say to this sycamine tree, 'Be rooted up, and be planted in the sea,' and it would obey you. "Will any one of you, who has a servant plowing or keeping sheep, say to him when he has come in from the field, 'Come at once and sit down at table'? Will he not rather say to him, 'Prepare supper for me, and gird yourself and serve me, till I eat and drink; and afterward you shall eat and drink'? Does he thank the servant because he did what was commanded? So you also, when you have done all that is commanded you, say, 'We are unworthy servants; we have only done what was our duty.'"
