Andrew the Fool-for-Christ
Blessed Andrew the Fool-for-Christ was born a Scythian and came to live in Constantinople as the slave of Theognostus, a protospatharios to Emperor Leo VI the Great (886-912), during the 10th-century. He was also the spiritual child of a Nicephorus, priest at the Church of St. Sophia in Istanbul during that time. He is commemorated by the Church October 2.
Blessed Andrew loved God's Church and the Holy Scriptures and he had a strong desire to devote himself totally to God. He took upon himself a very difficult and unusual ascetic feat of fool-for-Christ; that is, he acted as if he were insane.
Seeming to be insane, Andrew was brought to the Church of St. Anastasia for his care. There St. Anastasia appeared to him in a dream and encouraged him to continue his ascetic feat. He was driven off the church property because of his faked madness and had to live on the streets of the capital city, hungry and half-naked. For many years the saint endured mockery, insults, and beatings. He begged for alms and gave them away to the poor. The beggars to whom he gave his last coins despised him, but Andrew endured all his sufferings humbly and prayed for those who hurt him.
St. Andrew's holy wisdom and extraordinary spiritual beauty were revealed when he removed his mask of folly. This occurred when talking to his spiritual father, a presbyter of Hagia Sophia Church, or to his disciple Epiphanus.
For his meekness and self-control, the saint received from the Lord the gifts of prophecy and wisdom, saving many from spiritual perils. Like the apostle Paul, he was taken to the third sky and had the honor of seeing Lord Jesus Christ himself, angels and many holy saints, yet he was surprised not to see the Most Holy Virgin.
While praying at the Blachernae church, it was St. Andrew who, with his disciple, the Blessed Epiphanius, saw the Most Holy Mother of God, holding her veil over those praying under her Protection. The Church synaxarion states that upon seeing this vision, St. Andrew turned to his companion and asked: "Do you see, brother, the Holy Theotokos, praying for all the world?" Epiphanius answered, "I do see, holy Father, and I am in awe."
Blessed Andrew died in the year 936 at the age of 66.
During the Byzantine era, a number of writings appeared predicting the Apocalypse to be marked by the fall of Constantinople. While they were repeated in the 14th and 15th centuries, their origins most likely in the 10th, while the Eastern Roman Empire was still strong. Constantinople's destruction is described along these lines in the Life of Andrew the Fool. One of his disciples claims that Hagia Sophia would survive a great flood by "floating over waters," but St. Andrew explains instead that only the column (the obelisk) would survive because beneath its foundations are the Holy Nails which were used to crucify Jesus Christ. In this work, Andrew is depicted as predicting that the world's end would fall shortly after Constantinople's fall. citation needed
