XXVIII. That We Ought Not to Be Indifferent About Communicating.
But whosoever comes to you, let him be first examined, and then received: for ye have understanding, and are able to know the right hand from the left,1 and to distinguish false teachers from true teachers. But when a teacher comes to you, supply him with what he wants with all readiness. And even when a false teacher comes, you shall give him for his necessity, but shall not receive his error. Nor indeed may ye pray together with him, lest ye be polluted as well as he. Every true prophet or teacher2 that comes to you is worthy of his maintenance, as being a labourer in the word of righteousness.3
