Inevitably, when we look to the theological wisdom of the previous generations regarding the role of men in society, the work-place and the home, we come back to the importance of the practice of catechism. Instead of replacing or supplanting the role of the Bible in Christian education, catechism ideally serves as the basis for it. For the practice of catechism, as properly understood, is the Christian equivalent of looking at the box top of a jig-saw puzzle before one starts to put all of those hundreds of little pieces together. It is very important to look at the big picture and have it clearly in mind, so that we do not bog down in details, or get endlessly sidetracked by some unimportant or irrelevant issue. The theological categories given to us through catechism, help us to make sense out of the myriad of details found in the Scriptures themselves.
Catechism serves as a guide to better understanding Scripture.
That being noted however, we need to remind ourselves that Protestants have always argued that creeds, confessions and catechisms are authoritative only in so far as they faithfully reflect the teaching of Holy Scripture. This means that the use of catechisms, which correctly summarize biblical teaching, does not negate or remove the role of Holy Scripture. Instead, these same creeds, confessions and catechisms, as summary statements of what the Holy Scriptures themselves teach about a particular doctrine, should serve as a kind of spring-board to more effective Bible study. When this is the case, these confessions, creeds and catechisms are invaluable tools to help us learn about the important themes and doctrines that are in Scripture. The practice of catechism also serves as an important safeguard against heresy and helps to mitigate some of the problems associated with the private interpretation of Scripture.
