History of Together in the Mystery

Together in the Mystery grows out of San Francisco Theological Seminary’s Diploma in the Art of Spiritual Direction program, which draws students from across the United States and around the world.

In recent years the Diploma in the Art of Spiritual Direction program has attracted students from such countries as Korea, Japan, China, New Zealand, Germany, Kenya, and Switzerland — and Together in the Mystery has its roots in that fact.  Created out of a need for the Diploma in the Art of Spiritual Direction program to locate competent supervisors around the world, Together in the Mystery is a training program mobile enough to educate supervisors in their own geographical context.  In addition, its staff have enough training and experience to offer quality supervisor education.  Further, among many its many fine supervisors Together in the Mystery counts participants from eight US states as well as Canada, Japan, Korea, China, the Philippines, Northern Ireland, and Mexico
