Virtues of a Good Preacher

"A good preacher should have these qualities and virtues: first, to teach systematically; second, he should have a ready wit; third, he should be eloquent; fourth, he should have a good voice; fifth, a good memory; sixth, he should know when to make an end; seventh, he should be sure of his doctrine; eighth, he should venture and engage body and blood, wealth and honour, in the world; ninth, he should suffer himself to be mocked and jeered of everyone." Martin Luther in Table-Talk
