Isidore of Pelusium
Our venerable and God-bearing Father Isidore of Pelusium was a monastic in the deserts of Egypt, making his Mount Pelusium his home and the primary locus of his ascetical efforts. He died about the year 436, and his feast day in the Church is February 4.
Isidore was Egyptian by birth and from a prominent Alexandrian family, which included Alexandrian Patriarchs Theophilos and Cyril. He studied all the secular disciplines, but as a youth withdrew from the world, renouncing his riches and earthly glory, so that he might devote himself entirely to the spiritual life.
During his lifetime, he came to be a great and energetic defender of the Orthodox Christian faith, writing (according to the historian Nicephorus) more than ten thousand letters to numerous individuals, giving reproach, counsel, encouragement, comfort, and instruction.
At the time of the persecution of St. John Chrysostom, Archbishop of Constantinople, while the populace was split into two factions, one for Chrysostom and the other against, Abba Isidore sided with the golden-tongued saint. He wrote to Patriarch Theophilus that St. John was a great light of the Church, and he begged him to avoid rancor against the exiled archbishop.
In some of his many letters, St. Isidore is quoted as saying the following:
"It is more important to teach by a life of doing good than to preach in eloquent terms."
"If one desires that his virtues appear great, let him consider them small, and they will surely manifest themselves as great."
"First do and then teach, according to the example of our Lord Jesus."
"To live without speaking is better than to speak without living. For the former who lives rightly does good even by his silence, but the latter does no good even when he speaks. When words and life correspond to one another they are together the whole of divine philosophy."
