The Process of Admission to Ordained Ministry, in volumes for the early and Medieval periods, the Reformation period, and contemporary times, analyzes the liturgico-canonical institutions of the particular time and the complex structure of ordination ad the relational dimension of the ordained ministry in the Church. Ordination links ministry, local church, confession of faith and communion in a process that is also communitarian, liturgical and juridical, and, through these traits, sacramental. It examines how Christian ordination cannot be reduced to a rite of installation or the acceptance of a charge but is an ecclesial process whereby a Christian receives a charism for the edification of the Church.
