A unique situation exists in the Nordic countries where there is a Lutheran majority living in ecumenical cooperation with other churches and ecclesiastical communities. This book attempts to shed light on what the churches have discovered they hold in common and on areas where they recognise that there are divergencies between them, both in relation to ordination and ministry, and in particular to the theology and terminology of ordination. The book brings together the research and insights of 23 researchers from all the Nordic countries studying more than 200 different kinds of 'ordination' rites from the Orthodox and Roman Catholic as well as Lutheran and non-Lutheran protestant traditions. After an introduction to the churches in the Nordic countries, the book presents 19 case studies from the Nordic countries. The last part includes some general ecumenical and liturgical perspectives on ordination and rites presented by international researchers.
