Where did the practice of catechesis originate?

Catechesis was an age-old pedagogical method from classical education, which got picked up by the Reformers.

There are people whom you would not suspect who wrote catechisms. Bunyan wrote a catechism. We always talk about Pilgrim’s Progress, but he wrote a wonderful catechism. Charles Haddon Spurgeon also wrote a catechism. So, there’s a rich tradition, and if we’re not aware of it or cut ourselves off from it, that’s to our loss. There are wonderful catechisms, such as the old standards of the Westminster Shorter Catechism and the Heidelberg Catechism for our Dutch Reformed friends. These are great tools that can be very helpful.
