Catechism

A couple of months ago we decided to teach our kids catechism-which consists of key questions and answers on the christian faith. Ironically, we already had "The Shorter Catechism" book that was published in the '20's or '30's. I bought a new one anyway so as not to ruin the antique book. So far we have memorized the first 4 ques/answers. Cat knows the first one but, is slower on the others since they are wordier. Our goal is to learn 1 a week, during school time that may not work out but, definitely during the summer we can do that. There are 107 to memorize...wow!
The following are the first 4:
1. What is the chief end of man?
-Man's chief end is to glorify God, and to enjoy him for ever.
2. What rule hath God given to direct us how we may glorify and enjoy him?
-The Word of God, which is contained in the Scriptures of the Old and New Testaments, is the only rule to direct us how we may glorify and enjoy him.
3. What do the Scriptures principally teach?
-The Scriptures principally teach what man is to believe concerning God, and what duty God requires of man.
4. What is God?
-God is Spirit-infinite, eternal and unchangeable- in his being, wisdom, power, holiness, justice, goodness, and truth.
I'm excited about learning these biblical truths with the kids.
