Twenty-First Sunday After Pentecost

From the Introit:
All things are in Thy will, O Lord: and there is none that can resist Thy will: for Thou hast made all things, heaven and earth, and all things that are under the cope of heaven.

Epistle from Blessed Paul the Apostle to the Ephesians (6: 10-17):
Bretheren: Be strengthened in the Lord, and in the might of His power. Put you on the armour of God, that you may be able to stand against the deceits of the devil. For our wrestling is not against flesh and blood, but against principalities and powers, against the rulers of the world of this darkness, against the spirits of wickedness in the high places. Therefore, take unto you the armour of God, that you may be able to resist the evil day, and to stand in all things perfect. Stand therefore, having your loins girt about with truth, and having on the breastplate of justice, and your feet shod with the preparation of the gospel of peace; in all things taking the shield of faith, wherewith you may be able to extinguish all the fiery darts of the most wicked one. And take unto you the helmet of salvation, and the sword of the Spirit, which is the word of God.

Gospel (according to St. Matthew (18: 23-35)

At that time Jesus spoke to his disciples this parable: The Kingdom of heaven is likened to a king, who would take an account of his servants. And when he had begun to take the account, one was brought to him that owed him ten thousand talents: and as he had not wherewith to pay it, his lord commanded that he should be sold, and his wife and children, and all that he had, and payment to be made. But that servant falling down, besought him saying: Have patience with me, and I will pay thee all. And the lord of that servant being moved with pity, let him go; and forgave him the debt. But when that servant was gone out, he found one of his fellowservants that owed him a hundred pence: and laying hold of him, he throttled him saying: Pay what thou owest. And his fellowservant falling down besought him, saying: Have patience with me, and I will pay the all. And he would not; but went and cast him into prison till he paid the debt. Now his fellowservants, seeing what was done, were very much grieved; and they came and told their lord all that was done. Then his lord called him, and saith to him: Thou wicked servant, I forgave thee all the debt because thou besoughtest me; shouldst not thou then have had compassion also on thy fellowservant, even as I had compassion on thee? And his lord being angry delivered him to the torturers until he paid all the debt. So also shall my heavenly Father do to you, if you forgive not every one his brother from your hearts.
