The Priesthood: A Treatise in Six Books (Second Edition) is a classic theological work by Saint John Chrysostom, an early Church Father, containing a profound dialogue on the dignity, responsibilities, and difficulties of being a Christian priest. Written in the format of a letter to his friend Basil, it discusses the ideal qualities of a priest, spiritual perfection, and the importance of holy church service. The second edition is likely a modern reprint of a classic text that addresses these themes in detail, offering timeless insights into the spiritual life and church leadership. It is a fundamental guide to priestly life, discussing how a priest should live a holy life, fight against sin, and serve the people with wisdom and love, a work that remains relevant even though it was written in the 4th century.
