THE CHURCH UNDER INNOCENT III 451 France by leading the life of poverty themselves and by preaching and teaching, by argument and discussion. They met with little success, however, because the other clergy were suspicious of them as former heretics. Dominic now took up this idea of training a body of men to combat jheresy and teach the people the true faith.
