This resource is designed to be a "go-to-guide" for sponsors, trustees and other leaders in health care, education and social service ministries of the Catholic Church. It includes four parts that contain: the foundations of the ministry of sponsorship as rooted in Jesus' ministry; challenges and opportunities for the future; an invitation to partnership by all those who serve in leadership of these works of the church; models for sponsorship, both specific examples and generalized explanations of the predominant models being utilized for accountability; a discernment guide; and a 19-item appendix of resources that includes an annotated bibliography, glossary of terms, articles and examples of sponsorship agreements, mission assessment tools, formation curriculums and other documents that will provide insight into what is happening today in U.S. Catholic Ministries. This resource is provided in a binder so that ministries can add their own important documents.
