My work with the pastors and laypeople there deepened my resolve to lead a public life, but it also forced me to confront a dilemma that my mother never fully resolved in her own life: the fact that I had no community or shared traditions in which to ground my most deeply held beliefs. The Christians with whom I worked recognized themselves in me; they saw that I knew their Book and shared their values and sang their songs. But they sensed that a part of me remained removed, detached, an observer among them. I came to realize that without an unequivocal commitment to a particular community of faith, I would be consigned at some level to always remain apart, free in the way that my mother was free, but also alone in the same ways she was ultimately alone.
