Professor Gromada has provided fellow-theologians and researchers with a complete and accurate history of the different stages, transitions and influences which lead to the actual text on ministry in 'Baptism, Eucharist, and Ministry' (BEM) produced by the Faith and Order Commission of the World Council of Churches in January 1982 in Lima, Peru. In this serious and methodical exposition, both published and unpublished sources and documentation are utilized as well as the author-participant's own material. In addition, individual theologians and theological perspectives are identified and highlghted and the eventual direction of ecumenical discussions is fully described.
