Saint Anthony, the Father of monks, was born in Egypt in 251 of pious parents who departed this life while he was yet young. He began his ascetic life at a young age, and having learned from the ascetics outside his village, he departed deep into the Egyptian desert, where he lived in extreme fasting, unceasing prayer, and fierce conflicts with the demons. He reposed on January 17 in the year 356, having lived altogether some 105 years, attracting a multitude of imitators who admired him for his virtuous way of life and Christian example.
The following excerpt from The Life of Anthony by St. Athanasius the Great records a few of his encounters with pagan philosophers, by which he won over their admiration, despite his lack of education. He does this by demonstrating the futility of worshiping created things rather than the uncreated Creator, and the power and superiority of faith over reason.
By St. Athanasius the Great
And Anthony also was exceeding prudent, and the wonder was that although he had not learned letters, he was a ready-witted and sagacious man. At all events two Greek philosophers once came, thinking they could try their skill on Anthony; and he was in the outer mountain, and having recognized who they were from their appearance, he came to them and said to them by means of an interpreter:
"Why, philosophers, did you trouble yourselves so much to come to a foolish man?"
