The Catholic doctrine on original sin was dogmatized in the 16th century at the Council of Trent. Since then a lot has changed: the way of interpreting the first chapters of the Book of Genesis, the scientific paradigm describing the beginning of the world and human existence on earth, and finally the philo-sophical paradigm. This situation has contributed to various contemporary reinterpretations of the truth about original sin, despite the conservative posi-tion of the Church’s Magisterium. Among the various trends of contemporary reinterpretations of the doctrine of original sin, the author puts himself in the trend of reinterpretation based on the redemption story and tries to present the dogmatized teaching of the Church, taking into account the problems of the contemporary vision of the world and the scientific paradigm.
