The United States bishops' document Co-Workers in the Vineyard of the Lord is a vital resource for the ongoing development of lay ecclesial ministry. Building upon Co-Workers and affirming the recent renewal of the laity and the flowering of lay ministries, Reflections on Renewal contributes to efforts to reshape ministerial language and practices in the church today. It explores the theological and pastoral foundations of ministry, including how all ministry is rooted in the sacraments of initiation, and suggests ways of refining or redefining our understandings of lay ecclesial and ordained ministries so that we as church can respond more fully to the call of God in our lives and world. At the same time, the book recognizes that lay ministry developed organically as the work of the Spirit and is, foremost, a cause for rejoicing. This collection of essays is grounded in Fordham University's commitment to the church and its mission in the world. It honors the thousands of laypeople who have answered a call to serve the church in ministry.
