Venerable Isaac the Confessor, Founder of the Dalmatian Monastery at Constantinople

Saint Isaac, the founder of the Dalmaton Monastery (Μονή Δαλμάτων) at Constantinople, lived during the IV century, in the reign of Emperor Valens (364-378), who was an adherent of the Arian heresy.

Saint Isaac was tonsured as a monk when he was young, and through his ascetical struggles in the desert, he acquired every virtue. He was also found worthy of receiving the gift of prophecy from God. When he learned that Orthodox Christians were being persecuted, and their churches were being closed or destroyed, he left the wilderness and went to Constantinople to console and encourage the Orthodox, and to oppose the heretics. At that time, the barbarian Goths along the Danube River were waging war against the Empire. They had captured Thrace and were advancing toward Constantinople.

As Emperor Valens was leaving the capital with his soldiers, Saint Isaac cried out, “Emperor, reopen the churches of the Orthodox, and then the Lord will help you!”

The Emperor ignored the Saint's words and continued on his way. The next day, Isaac ran out to warn the Emperor again. Valens, moved by Isaac's boldness and sincerity, was almost persuaded to do as he asked. However, one of his advisors (an Arian) convinced him not to grant the Saint's request. On the third day the Saint stood in Emperor's path and grabbed the bridle of his horse, repeating his request; sometimes in a pleading tone, and sometimes in a reproachful manner. He also threatened divine retribution if Valens did not honor his request. Offended by Isaac's audacity, Valens had him thrown into a deep pit filled with mud and thorns, from which it was impossible to escape.

With God’s help, however, Saint Isaac was able to get out of the pit. He overtook the Emperor and said, “You wanted to destroy me, but Angels pulled me out of the mire. Hear me! Reopen the churches for the Orthodox and you shall defeat the enemy. If you do not heed me, however, then you shall not return. You will be captured and burned alive. Learn from experience that it hurts you to kick against the goads" (Acts 26:14).1

The Emperor was astonished at the Saint's boldness and ordered his attendants Saturninus and Victor to seize the monk and keep him in prison until his return.

Saint Isaac’s prophecy was soon fulfilled. On August 9, 378 a fierce battle was fought near Adrianoupolis, during which the imperial army was defeated, and many excellent generals were killed. Valens and his chief of staff took refuge in a barn filled with straw, and the attackers set it ablaze. The two men were burnt alive, just as Isaac had foretold.

Back in Constantinople, some of the soldiers who survived the battle came to Isaac's prison cell and said to him, "Prepare to make your defense before the Emperor, who is coming to put you on trial."

Isaac replied, "The stench of his charred bones has assailed my nostrils for more than seven days."

When this event became known, the clergy and the people released Saint Isaac from prison. With great respect, they approached him in order to receive his blessing, Then the holy Emperor Theodosios the Great (379-395) came to the throne. On the advice of Saturninus and Victor, he summoned the Elder, according him much honor. Obeying his instructions, he banished the Arians from Constantinople and restored the churches to the Orthodox. Saint Isaac wanted to return to his desert, but Saturninus and Victor begged him not to leave the city, but to remain and protect it by his prayers.

Saint Isaac was present at the Second Ecumenical Council at Constantinople in 381, where he was responsible for much of its success because of his zeal in defending Orthodox doctrine.

Saturninus built a monastery for the Saint in Constantinople, where monks gathered around him. Saint Isaac was the monastery’s Igoumen and spiritual guide. He also nourished laypeople, and helped many of the poor and suffering.

Sensing his approaching death, Saint Isaac appointed Saint Dalmatios (August 3) to succeed him as the Igoumen. The monastery was later renamed for Saint Dalmatios (Δαλμάτιος).

Saint Isaac went to the Lord in the year 383. He is also commemorated with Saints Dalmatios and Faustos on August 3. In Greek usage, however, Saint Isaac is commemorated on May 30.
