In the systematic study of the Bible, OT and NT, this course aims to introduce into the world of the apostle Saint Paul and his letters in order to understand and assimilate their theological content. Two stages mark the route of the course. [I] A first part serves as a general introduction: evaluation of the figure of the apostle, general consideration on his writings, and more relevant data on Paul’s life. [II] The second part presents the theological message of each of the letters of the corpus paulinum.
