A word on the use of catechisms:

A catechism is a summary of the basic doctrines and beliefs of a religious sect. In a Christian context, traditionally catechisms were organized in a question and answer format, believing that this was the way in which Christianity was originally disseminated and taught.

The term “catechism” is derived from the Greek katecheo, which in the New Testament refer to teaching someone in an orderly or systematic way,  by word of mouth, in the form of a dialogue–question and answer.  We find this use of the word in texts like Luke 1:4; Acts 18:25; 1 Corinthians 14:19 and Galatians 6:6.  We often speak of “to catechize someone.”
