Romans 4.13-25 (Epistle)

13For the promise, that he should be the heir of the world, was not to Abraham, or to his seed, through the law, but through the righteousness of faith. 14For if they which are of the law be heirs, faith is made void, and the promise made of none effect: 15Because the law worketh wrath: for where no law is, there is no transgression. 16Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham; who is the father of us all, 17(As it is written, I have made thee a father of many nations,) before him whom he believed, even God, who quickeneth the dead, and calleth those things which be not as though they were. 18Who against hope believed in hope, that he might become the father of many nations; according to that which was spoken, So shall thy seed be. 19And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sara’s womb: 20He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God; 21And being fully persuaded that, what he had promised, he was able also to perform. 22And therefore it was imputed to him for righteousness. 23Now it was not written for his sake alone, that it was imputed to him; 24But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead; 25Who was delivered for our offences, and was raised again for our justification.

Matthew 7.21-23 (Gospel)

21Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. 22Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? 23And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.

St Isaac, founder of the Dalmatian Monastery at Constantinople (383)

While a hermit in the east, Isaac heard that the Arians, supported by the Emperor Valens, were persecuting Orthodoxy. Leaving his seclusion, he traveled to Constantinople, where he lived in a small hut. He confronted the Emperor, telling him that if he did not cease his persecutions and embrace the true Faith, disaster would befall him. The Emperor ignored his words, and shortly thereafter was killed in a battle with the Goths. The Emperor Theodosius the Great then came to the throne, restoring peace to the Church. Hearing of Isaac and his prophecy, the Emperor sent for Isaac and prostrated before him. Isaac wished to return to the desert, but was persuaded to remain as a monk in Constantinople. He took part in the Second Ecumenical Council, where he shone in zeal for the Faith; the Third Ecumenical Council made him archimandrite over all the monasteries in the City. (Some say that the monastery founded by him is called the Dalmatian Monastery because it was built by Dalmatus, a wealthy nobleman of the City; others say that it was founded by St Isaac himself and later took its name from Abbot Dalmatus, who succeeded Isaac). In his own lifetime St Isaac was known far and wide as a wonderworker and one endowed with the gift of prophecy.

Saint Isaac is also commemorated in August 3, along with Dalmatus and his son Faustus.

St Macrina, grandmother of St Basil the Great (4th c.)

“The grandmother of St Basil the Great, she was outstanding for her intellect and piety. She was a disciple of St Gregory the Wonder-worker of Neocaesarea. In the reign of Diocletian, she abandoned her home and hid in the forests and desert places with her husband, Basil. Although their home was confiscated, they felt no pangs of regret. Stripped of everything except their love for God, they settled in an ancient forest and spent seven years there. By God’s providence, goats would come down from the mountains and provide them with food. They both died peacefully in the fourth century, after great sufferings for the Christian faith.” (Prologue)
