Father Chris Pietraszko has been thinking about sin and redemption for the last year and a half as he has been writing a series of articles that will become a book. Relying on the Gospel, Catholic Doctrine, Thomas Aquinas, and his experience in the confessional, Father Chris explains the mechanism of sin, how it works in our lives, and how it is to be defeated. He reflects on his experience as a confessor and explains the relationship between the deadly and venial sins.

Krzysztof Odyniec is a historian of Medieval and Early Modern Europe; he is also the host of the 'Almost Good Catholics' podcast.
