St. Augustine

The Father of Catechetics describes catechizing the ignorant in this way:

“The best method for instructing ignorant men in Christian doctrine, one that will bear much fruit is to ask questions in a friendly fashion after the explanation; from this questioning one can learn whether each one understood what he heard or whether the explanation needs repeating. In order that the learner grasp the matter, we must ascertain by questioning whether the one being catechized has understood, and in accordance with his response, we must either explain more clearly and fully or not dwell further on what is known to them etc. But if a man is very slow, he must be mercifully helped and the most necessary doctrines especially should be briefly imparted to him.”
