What does it mean to think Orthodox? What are the unspoken and unexplored premises and presumptions underlying what Christians believe? Orthodox Christianity is based on preserving the mind of the early Church, its *phronema*. Dr. Jeannie Constantinou brings her more than forty years’ experience as a professor, Bible teacher, and speaker to bear in explaining what the Orthodox *phronema* is, how it can be acquired, and how that *phronema* is expressed in true Orthodox theology — as practiced by those who are properly qualified by both training and a deep relationship with Christ.
