Seven sessions on Christian unity based around a Covenant for Mission. Each of the seven units is constructed in such a way as to enable it to be adapted to the context in which it is used. The sessions differ from one another in detail but the overall pattern is a statement of the theme and a prayer; a Bible reading or readings, followed by notes for a sermon or a study group introduction; discussion starters and suggestions for prayer. The Appendix consists of a selection of ideas or quotations relevant to each chapter. The sessions may be used ecumenically, or by individual congregations or groups of churches.
