Since a teacher of catholic truth should instruct not only the advanced but beginners as well - as St. Paul says, "Like babes in Christ I fed you milk and not meat" (I Cor. 3:1) - our intention in this work is to convey the content of the Christian religion in a way fit for the training of beginners. We have seen that novices in this study are greatly hindered by the various writings on the subject. They are hindered partly because of the multiplication of useless questions, articles and arguments in these writings; partly because the order in which essential material is delivered in these writings is determined, not by the nature of doctrine itself, but by the books on which the writings are commenting; and partly because frequent repetition has bred boredom and confusion in the minds of hearers.
Eager to avoid these and other pitfalls we shall now attempt to examine the content of sacred doctrine briefly and clearly, so far as the material allows, twisting in God's aid.
