1. Our Holy Father Isaac the Confessor.
In the time of the Emperor Valens, the Arians persecuted Orthodoxy fiercely with the Emperor's encouragement. Isaac, a hermit somewhere in the East, heard of the persecution, left his desert and went to Constantinople to encourage the faithful and denounce the heretics. Valens arrived in the north at that very time with his army, to meet the Goths who had come down from the Danube into Thrace. Isaac went out and stood before him, saying: 'Open the churches to those of the true Faith, 0 Emperor, and God will bless thy path', but the Emperor turned a deaf ear to the elder and went on his way. Isaac spoke out before the Emperor on the next day also, repeating his warning, and the Emperor almost hearkened to him, but one of his advisors, a follower of the Arian heresy, thwarted him. Isaac spoke before the Emperor again on the third day, seizing the Emperor's horse by the reins and pleading with him to grant freedom to the Church of God and to escape divine punishment by acceding to his request. The enraged Emperor ordered that the elder be thrown into a waste place full of thorns and mud, but three angels appeared and pulled him out of the swamp. St Isaac appeared before the Emperor on the fourth day, and foretold a terrible death if he did not give the Orthodox freedom: 'I tell thee, my Emperor, that thou shalt lead thy troops out upon the barbarians, but thou shalt not be able to withstand them. Thou shalt flee before them, but shalt thyself be taken captive and burned alive.' And so it all came to pass. The barbarians mowed the Greek force down like grass, and the Emperor fled with his Aryan counselor, and hid in a hamper. The barbarians arrived at the spot and realized where the Emperor was hiding. They surrounded the hamper and set fire to it, burning both the Emperor and his counselor. The Emperor Theodosius the Great then came to the throne. He heard of Isaac and of the prophecy that had been fulfilled, and, sending for him, prostrated himself before him. And so peace came to reign in the Church and the Arians were banished. Isaac desired to return to his desert, but he was persuaded to remain in Constantinople. A certain influential citizen, Saturninus, built him a monastery where the elder laboured in asceticism until his death, performing many wonders. The community overflowed with monks and became a great monastery. Before his death, Isaac appointed a pupil of his, Daimatus (after whom the monastery was later named), as abbot. The elder Isaac, who had found such favour with God, entered into eternity in the year 383, to rejoice forever in the vision of the face of God.
2. St Macrina.
The grandmother of St Basil the Great, she was outstanding for her intellect and piety. She was a disciple of St Gregory the Wonderworker 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.
