Prophets cannot be deliberately formed by a predictable process. Moses had what Martin Buber called an "I/Thou" encounter with God and was able to express some of its content to the people he led. St. Paul famously had an I/Thou encounter with Jesus on the road to Damascus. The Buddha had an I/Thou encounter under the Bodhi Tree. There was no classroom component or ordination. The weakness of religious education programs and seminaries across all denominations is that they expect to re-create Moses through a linear process when they should be focused on re-creating Aaron. The I/Thou encounter cannot be conjured or taught.
Lacking an authentic Moses we tend to look for our prophets and moral guides among celebrities, politicians, and worse. Lacking an authentic Moses we abandon even Aaron and embrace the secular.
