In the first article, “Bap: A Critical Comparative Analysis of the Understanding of Sin in Thai Culture and in the Catechism of the Catholic Church (CCC),” Mongkol Wongwai, O.M.I. presents an interesting analysis of the Thai concept of bap vis-à-vis the Catholic doctrine of sin. He makes use not only of dictionary and literary sources but also mines cultural expressions such as folk tales and popular songs as well as films, soaps and television dramas. Beyond the attractiveness of its creative and quite novel methodology, however, his research points out profound ways by which the intersection of the notions of bap and sin can mutually challenge and enrich each other, thus leading not only to a better understanding of transgression but even of God, humanity and the world. – from the Editor’s Preface
