Now when Christ did not hesitate to inflame still more, by keen provocation, wicked and malicious persons, let us learn from his example, that we ought not to be exceedingly solicitous to please every one by what we say and do. His disciples, however—as is usually the case with ignorant and unlearned people—no sooner perceive the result to be unfavorable, than they conclude that Christ’s reply had been unseasonable and improper. For the object of their advice was, to persuade Christ to soothe the rage of the Pharisees by softening the harsh expression which he had employed.
