Building Christian Communities: Strategy for Renewing the Church, by Stephen B. Clark, argues that contemporary churches often function as inefficient organizations rather than formative environments, leading to a decline in genuine Christian living; the book proposes shifting to an environmental model, emphasizing holistic community, pastoral leadership, basic Christian communities (BCCs), and priorities focused on faith and mission to foster authentic spiritual growth and renewal, particularly within the Catholic Church context but applicable broadly. Fostering close-knit, covenant-based communities (like those in The Word of God movement) encourages members to live out their faith and support each other, often as a complement to their existing church involvement.
