St. John Chrysostom delivered nine homilies on repentance in Antioch of Syria sometime between 386 and 387. With conviction and certitude, he preached that repentance was a necessity for both the sinner and the righteous man. This volume presents Chrysostom's homilies on repentance and includes a sermon on almsgiving that he preached in Antioch during the winter months in 387. Chrysostom's work reveals that repentance is an indestructible pillar of the All-Holy, Universal and Immutable Church of Christ. He believed that repentance is the liturgical tool that rejuvenates sinners and admits them into the life-giving Eucharist where they experience fully and dynamically the concrete presence of God.The powers of repentance have rich biblical roots, and Chrysostom masterfully weaves his teaching with a plethora of Old and New Testament citings. From Scripture, the reader learns that repentance is never confined to the eucharistic context--it becomes a way of life for the believer. The daily applications of repentance, such as almsgiving, fasting, remorse over personal sins, humility, prayer, and attending Church, suggest that a person's entire life has an ecclesial character. Chrysostom preached that the whole experience of a true life in Christ is repentance that culminates in metanoia--the total change and renewal from the heart and mind of sin to "the mind of Christ" (1 Cor. 2:16). In his introduction to the homilies, Fr. Gus Christo includes a succinct biography of Chrysostom within which he sets the homilies in their chronological context. He also provides an overview of repentance and discusses the ecclesiological nature of Chrysostom's theology.
