From the UCC -
"Faith formation is at the heart of what the Christian life is all about. In many ways, we engage in the practices of our daily lives and the rituals of our faith communities—through worship, mission, working for justice and peace, evangelism, and education—so that our faith may be nurtured, enlivened, sustained, and formed. In this regard, the imagery offered by the prophet Isaiah of Potter God forming humanity, God's created own, is an appropriate vision for how we might view the ministry of faith formation.
In the United Church of Christ, we can understand faith formation to be "an engaged process of learning and practice integrated throughout all aspects of congregational and daily life." This definition highlights the initiative and action we must take in our own faith formation. In essence, we become clay so that we are formed and transformed by the Holy and by one another. But throughout all of our doing and being, we are reminded that God's "hands" are continually present in our efforts to gain both "head" knowledge found in education and learning and "heart" wisdom discovered through prayer, ritual, and practice."
