When many Christian congregations are asking, "How can we draw new members into our midst?" the authors reframe the question: "How can congregations make new disciples and deepen the faith of long-time Christians?" Rediscovery of the early church catechumenate provides a means to form new disciples in today's culture. Inspiring case studies of four congregations emphasize the contextual flexibility of adult faith formation. Interviews with catechumenal leaders and participants in adult faith formation reveal how a catechumenate that is central to congregational life can energize and orient the people of God toward the mission of God. Opening windows into congregational life, especially at worship, those who had journeyed through the adult faith formation process describe their experiences and the profound changes that took place in them. Adult faith formation is a journey—not a program—of belonging, believing, and behaving that draws people into Christ's orbit for life. As one participant said, "For the first time I understood what it meant to be a Christian." Through the adult catechumenate she heard the voice of Christ, calling her to new life and a rich baptismal identity.
