Hebrews 3.5-11, 17-19 (Epistle)

5And Moses verily was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after; 6But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end. 7Wherefore (as the Holy Ghost saith, To day if ye will hear his voice, 8Harden not your hearts, as in the provocation, in the day of temptation in the wilderness: 9When your fathers tempted me, proved me, and saw my works forty years. 10Wherefore I was grieved with that generation, and said, They do alway err in their heart; and they have not known my ways. 11So I sware in my wrath, They shall not enter into my rest.) 17But with whom was he grieved forty years? was it not with them that had sinned, whose carcases fell in the wilderness? 18And to whom sware he that they should not enter into his rest, but to them that believed not? 19So we see that they could not enter in because of unbelief.

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.
