Canon 3 Clergy and monks may not manage worldly business

It has come to the holy synod that some of those enrolled in the clergy, for base gain, become lessees of other men's estates and take on worldly business under contract, neglecting the service of God, while slipping into the houses of worldly men and taking on the management of properties out of love of money. The holy and great synod has therefore decreed that henceforth no one, not a bishop, not a cleric, not a monk, is either to lease estates or to thrust himself into the worldly administration of affairs; unless perhaps he be called by the laws to the unavoidable guardianship of minors, or the bishop of the city should permit him to take care of ecclesiastical affairs, or of orphans or widows unprovided for, and of those persons most in need of ecclesiastical help, for the fear of God. And if anyone should henceforth attempt to transgress what has been decreed, let such a one be subject to ecclesiastical penalties.
