Catechising has lost its appeal today. Many churches and families, even Christian families, have dispensed with it. Rutherford's Catechism is ideal for family or church use. His answers are often pithy, suggestive and always Biblical. The catechism forms a compact Body of Divinity, a little primer of theology. Catechising is an excellent way to teach children beliefs. Rutherford knew its value and was careful to catechise his flock regularly in order to bring them to maturity and understanding in the things of Christ.
