He was born at Antioch, Asia Minor (modern Syria) around 347 A.D. John's father died when he was young, and he was raised by a very pious mother.
He studied under the pagan Libianus, most famous orator of his day. He devoted himself to an ascetic life, and he was baptized around 369 and he was ordained reader. For two years he lived in a cave near Antioch, but his health being impaired by austerity, he returned to the city.
He was a preacher and priest for a dozen years in Syria. While there he developed a stomach ailment that troubled him the rest of his life. He had been ordained priest in 386, and in the twelve years that followed John was engaged chiefly in preaching and writing. It was for his sermons that John earned the title "Chrysostom" (golden mouthed). They were always to the point, explained the Scriptures with clarity, and sometimes went on for hours.
In 398 he was elevated to the See of Constantinople, a move that involved him in imperial politics and where he experienced popular resentment by his sweeping reforms.
As a result John was deposed and exiled in 403, by Theophilus, Patriarch of Alexandria. John was recalled by the empress. John criticized the rich for not sharing their wealth, fought to reform the clergy, prevented the sale of ecclesiastical offices, called for fidelity in marriage, and he encouraged practices of justice and charity. John's sermons caused nobles and bishops to work to remove him from his diocese and he was exiled a second time from his diocese in 404.
John was banished to Pythius, but died on the way in 407. His relics are in the choir chapel of Saint Peter's Basilica, Rome.
Whoever denigrates marriage also diminishes the glory of virginity. Whoever praises it makes virginity more admirable and resplendent. What appears good only in comparison with evil would not be truly good. The most excellent good is something even better than what is admitted to be good.
You have tasted the Blood of the Lord, yet you do not recognize your brother,. . . . You dishonor this table when you do not judge worthy of sharing your food someone judged worthy to take part in this meal. . . . God freed you from all your sins and invited you here, but you have not become more merciful.
What prayer could be more true before God the Father than that which the Son, who is Truth, uttered with His own lips?
It is possible to offer fervent prayer even while walking in public or strolling alone, or seated in your shop...while buying or selling...or even while cooking.
It is ever thus; the more you envy your brother, the greater good you confer upon him. God, who sees all, takes the cause of the innocent in hand, and, irritated by the injury you inflict, deigns to raise up him whom you wish to lower, and will punish you to the full extent of your crime.
