iPhone
A catechism in the hands of every child in the Americas.
That is the dream behind this app. Martin Luther's Small Catechism says in a few words what a Christian believes: the Ten Commandments, the Creed, the Lord's Prayer, Baptism, Confession and the Lord's Supper. For five hundred years it was learned by heart. Here it is learned through play.
THE CHALLENGE
Each lesson is a few short exercises: put the words of the commandment in order, complete the explanation, answer what it means. You move along a path of 40 lessons, earn points and open a chest at the end of each unit. Before you know it, you know it by heart.
WHAT'S INSIDE
• The whole Small Catechism: Commandments, Creed, Lord's Prayer, Baptism, Confession and the Lord's Supper.
• Bible stories read aloud.
• Passages from Luther's Large Catechism in every lesson.
• A daily wheel with questions, jokes and readings.
• Contests in class, with the teacher, or with the family.
• Reformation hymns to listen to inside the app.
• A finder for confessional Lutheran churches in more than 40 countries.
• Lives, streaks and Reformation characters to personalize.
• Lessons work offline.
• In English, Spanish and Portuguese.
WHO IT IS FOR
For children preparing for confirmation. For parents who want to teach at home. For Sunday school teachers. And for any adult who never had the chance to learn it.
