2 Thessalonians 2.13-3.5 (Epistle)

13But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth: 14Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ. 15Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle. 16Now our Lord Jesus Christ himself, and God, even our Father, which hath loved us, and hath given us everlasting consolation and good hope through grace, 17Comfort your hearts, and stablish you in every good word and work.

1Finally, brethren, pray for us, that the word of the Lord may have free course, and be glorified, even as it is with you: 2And that we may be delivered from unreasonable and wicked men: for all men have not faith. 3But the Lord is faithful, who shall stablish you, and keep you from evil. 4And we have confidence in the Lord touching you, that ye both do and will do the things which we command you. 5And the Lord direct your hearts into the love of God, and into the patient waiting for Christ.

Luke 18.31-34 (Gospel)

31Then he took unto him the twelve, and said unto them, Behold, we go up to Jerusalem, and all things that are written by the prophets concerning the Son of man shall be accomplished. 32For he shall be delivered unto the Gentiles, and shall be mocked, and spitefully entreated, and spitted on: 33And they shall scourge him, and put him to death: and the third day he shall rise again. 34And they understood none of these things: and this saying was hid from them, neither knew they the things which were spoken.

Holy Martyr Mercurius of Smolensk (1238)

He was a soldier from Byzantium, one of the defenders of Smolensk when it was besieged by the Tatars in 1238. One day the Mother of God appeared to Mercurius and told him that the Tatars were preparing a surprise attack — and, further, that he must take up arms and attack the enemy singlehandedly. Placing all his trust in God, the lone soldier threw himself against the Tatar host crying ‘Most Holy Mother of God, help me!’ He was quickly surrounded and cut down, and it appeared that his action had been as foolhardy as it had seemed, when a woman at the head of a glorious host, all of them surrounded by light, appeared and threw back the Tatar army. The next morning the people of Smolensk found the ground covered with the bodies of their enemies. They buried Mercurius in the Cathedral, where he has been venerated as a Martyr ever since.
