The Larger Catechism, written primarily by Dr. Anthony Tuckney, professor of divinity and vice-chancellor of Cambridge University, was designed for public exposition from the pulpit.
The Shorter Catechism, primarily the work of the Reverend John Wallis, an eminent mathematician who later became professor of geometry at Oxford University, was written for the education of children.
Both deal with questions of God, Christ, the Christian life, the Ten Commandments, the sacraments, and the Lord's Prayer; unlike most earlier catechisms, neither contains a section on the Apostles' Creed. Especially famous is the first question and answer of the Shorter Catechism.
Q.: What is the chief end of man?
A.: Man's chief end is to glorify God and enjoy him forever.
