It is incumbent upon the Trustees of the House of Justice to take counsel together regarding those things which have not outwardly been revealed in the Book, and to enforce that which is agreeable to them. God will verily inspire them with whatsoever He willeth, and He, verily, is the Provider, the Omniscient.
