Cymboyton (sim boy' ton), established a school of religious philosophy near the ancient Silk Road city of Urmia. A large lecture amphitheatre was situated on the largest of a group of islands, a short distance offshore. The building was dedicated to the "spirit of religion." More than thirty religions and religious cults were represented on the faculty. These teachers of the various religions made a great effort to show how similar their religions were in regard to the fundamental things of this life and the next. There was but one doctrine which had to be accepted in order to gain a seat on this faculty. Every teacher must represent a religion that recognized God or some sort of Supreme Deity. Any teacher exhibiting intolerance, a contentious spirit, or any other disposition to interfere with the smooth running of the community was unceremoniously dismissed. On several occasions Jesus participated in these discussions, and Cymboyton arranged with Jesus to sojourn with them for two weeks and give twenty-four lectures on "The Brotherhood of Men." Jesus also conducted twelve evening sessions of questions, discussions, and debates on his lectures. Jesus taught in Urmia during the spring of A.D. 25.
