Saint Theodore the Studite on Instructing Others

Since there are many and diverse characters, the method of instructing should also be implemented accordingly. For in the way that one person is healed, a different person might be harmed; in the manner one is benefited, another is destroyed; and with the words that someone is edified, it happens that another is damaged.
