The New City Catechism is a free resource that helps children and adults learn the core doctrines of the Christian faith through 52 questions and answers — one for each week of the year.^1 Tim Keller and Sam Shammas adapted it from Calvin's Geneva Catechism, the Westminster catechisms, and the Heidelberg Catechism.^2
A joint project of The Gospel Coalition and Crossway, the mobile app pairs each question with an ESV reading, a short prayer, and commentary from pastors including John Piper, Timothy Keller, and Kevin DeYoung.^3 Children's mode offers shorter answers and kid-friendly songs that make memorization natural.^3
Print companions sit alongside the app. The original book holds short and long forms of all 52 Q&As. The Devotional edition, edited by Collin Hansen, adds Scripture, prayer, and voices from Augustine, Calvin, and Luther beside the contemporary pastors.^5 Crossway also publishes a 52-lesson Curriculum for children ages 8–11.^6
Translations are available in many languages, from Arabic and Chinese to Uyghur and Vietnamese.^7 Keller wrote that catechesis takes truth deep into our hearts, so we think in biblical categories as soon as we can reason — God's Word "dwelling in us richly" (see Col. 3:16).^2
