During the long and impressive career of prof. Lambert Leijssen interesting ideas about sacraments, liturgy, pastoral theology, and spirituality were crystallized. It would be sad if the generations after prof. Leijssen would not be concerned anymore about these ideas. Therefore, the contributions in this book in one way or another reflect prof. Leijssen's major theological concerns. They have been taken up in three parts. In the first part, Louis-Marie Chauvet, Jean-Yves Lacoste, George S. Wogul, and Paul Post engage themselves in thoroughgoing fundamental reflections on the sacraments and the liturgy. The second part consists of four contributions dealing with individual sacraments. Jozef Lamberts, Joris Geldhof, Stijn Van den Bossche, and Thomas Knieps-Port le Roi respectively dwell on the sacraments of initiation, the Eucharist, and marriage. The third part contains reflections on the crossroads of sacramental theology, moral theology, and pastoral theology. Andre Haquin, Susan K. Roll, Annemie Dillen, and Marcel Broesterhuizen show in a very leijssenian way that sacraments always point to concrete life situations.By way of introduction to this volume, Matthijs Lamberigts' laudatio pronounced at the solemn celebration of prof. Leijssen's retirement has also been included.
