Gray Fitzgerald has been active in lay ministry and social services for much of his life. He volunteered in Ecuador with the Peace Corps, was a lay leader in an Atlanta inner-city church, served with a nonviolent ecumenical group in wartime Nicaragua, headed up volunteer construction for an Atlanta inner-city housing program, visited inmates throughout the Georgia prison system, counseled individual and families coping with mental illness, and pastored two small United Church of Christ congregations in New Hampshire. In retirement, he continued to live in NH and was active in the UCC's peace and justice activities. In recent years, he has focused on writing a book concerned with his belief that rather than the church converting our society to the values of our faith regarding money, property, and wealth, the culture has instead converted the church to the values of the culture in those areas.
