1 Thessalonians 1.1-5 (Epistle)

1Paul, and Silvanus, and Timotheus, unto the church of the Thessalonians which is in God the Father and in the Lord Jesus Christ: Grace be unto you, and peace, from God our Father, and the Lord Jesus Christ. 2We give thanks to God always for you all, making mention of you in our prayers; 3Remembering without ceasing your work of faith, and labour of love, and patience of hope in our Lord Jesus Christ, in the sight of God and our Father; 4Knowing, brethren beloved, your election of God. 5For our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance; as ye know what manner of men we were among you for your sake.

Luke 17.20-25 (Gospel)

20And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation: 21Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you. 22And he said unto the disciples, The days will come, when ye shall desire to see one of the days of the Son of man, and ye shall not see it. 23And they shall say to you, See here; or, see there: go not after them, nor follow them. 24For as the lightning, that lighteneth out of the one part under heaven, shineth unto the other part under heaven; so shall also the Son of man be in his day. 25But first must he suffer many things, and be rejected of this generation.

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.

Great Martyr Mercurius (ca. 259)

He was born in the province of Asia, to a Scythian who had secretly converted to Christianity. Like his parents, he was a secret follower of Christ, serving as a legionary in the Roman army during the reign of the Emperor Decius. During a campaign, an Angel appeared to him, gave him a sword and told him to go into battle trusting in Christ’s help. Mercurius plunged into battle, fought his way alone through the enemy lines, and reached the barbarian commander Rigas, whom he killed. Upon the death of their chief the barbarians scattered and the victory was won.

The Emperor, hearing of the young soldier’s exploits, promoted him to a position at court. There, lulled by the pleasures and honors of the court, Mercurius forgot his duties to Christ his King. One night the same Angel who had given him the sword appeared to him once again and reminded him of the sword that Christ had given him, an emblem of the battle of martyrdom that he was about to enter. The next day Mercurius, now returned to his senses, refused to offer sacrifice to the gods. When called before the Emperor, he boldly proclaimed Christ and threw off his badges of office. He was thrown in prison and subjected to cruel tortures, all of which he bore with peace and joy, encouraged by the Angel who appeared to him again to offer comfort and encouragement. After long torment he was beheaded in Caesarea in Cappadocia, at the age of twenty-five.
