2 Corinthians 8.1-5 (Epistle)

1Moreover, brethren, we do you to wit of the grace of God bestowed on the churches of Macedonia; 2How that in a great trial of affliction the abundance of their joy and their deep poverty abounded unto the riches of their liberality. 3For to their power, I bear record, yea, and beyond their power they were willing of themselves; 4Praying us with much intreaty that we would receive the gift, and take upon us the fellowship of the ministering to the saints. 5And this they did, not as we hoped, but first gave their own selves to the Lord, and unto us by the will of God.

Luke 10.19-21 (Gospel)

19Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you. 20Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven.

21In that hour Jesus rejoiced in spirit, and said, I thank thee, O Father, Lord of heaven and earth, that thou hast hid these things from the wise and prudent, and hast revealed them unto babes: even so, Father; for so it seemed good in thy sight.

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.
