This book is aimed at groups - communities, parishes, institutions, couples, teams, students, young adults, etc. - who wish to grow in communion and make decisions together. The book is based on a wealth of experience, shares numerous examples and provides a "toolbox" that has proved its worth. Esdac is a Christian, Ignatian, international association that puts Ignatian spirituality at the service of groups and offers, in various ways, a journey of discernment inspired by the Spiritual Exercises of Saint Ignatius to associations, communities, families, couples and groups. They encourage participants to learn to communicate better with each other, so that everyone is listened to and dares to express themselves. They help to discern the call that the Lord addresses to them today, by listening to each of the members and to the whole group. The group explore directions together and make mature decisions together. This comprehensive guide will help leaders to implement the programme in practice.
