*A Modern Sinner’s Guide for the Third Millennium* by the National Catholic Register’s award-winning editorialist Angelo Stagnaro makes sin understandable to modern audiences and gives practical advice on how to identify and avoid sin in one’s life, deal with temptation, and how to evangelize others unaware of sin’s enormity and its grave nature. Presenting chapters on the foundations of Christianity, the nature of sin, the pursuit of holiness, the Ten Commandments, the seven deadly sins and new deadly sins, the sins against the Holy Spirit, ultimate sins, the unforgiveable sin, and the Sacrament of Reconciliation, this book provides an in-depth look on more than 70 sins from a theological and spiritual perspective, together with the consequences of sins and remedies for them. The book uniquely addresses the ten delicts and the new seven deadly social sins promulgated in 2008 by the Vatican. It also has sections on Purgatory, Hell, Divine forgiveness, indulgences, the nature of good and evil, and the Christian spiritual quest. A Modern Sinner’s Guide for the Third Millennium is suitable for several audiences including RCIA catechumens, catechists, homilists, apologists, canonists, people interested in exploring different forms of Christian spirituality, those interested in comparative religions and spiritual traditions, and Christians interested in developing their own spiritual life. The book has been granted the Nihil Obstat and Imprimatur by the Catholic Archdiocese of New York. It can also be found at the Vatican libraries.
