In the Name of the Church: Vocation and Authorization of Lay Ecclesial Ministry presents insights generated in the 2011 Collegeville National Symposium on Lay Ecclesial Ministry, a gathering designed to prioritize the theological foundations for vocation and authorization in lay ecclesial ministry, and make recommendations to advance excellence in this expanding ministry. The essays presented by seven theologians at the Symposium are included, along with thoughtful input drawn from the experiences of lay and ordained ministers who gathered to amplify the voice and strengthen the national will to promote effective ecclesial leadership practices identified within Co-Workers in the Vineyard of the Lord.
