The main purpose of this research was to explore the ways the members of church-based small groups of various denominations in Southern California have experienced transformative learning, and to identify the factors that contribute to that experience. A qualified research was conducted. Purposeful sampling was used and data were collected through semi-structured interviews. A total of 22 people from six different denominations participated. Ten major themes came up as factors that foster transformative learning: relationships, Bible, God, good examples, problems, ministry, Christian literature, willingness, preaching of the church, and church retreats. Implications are presented at the end.
