New City Catechism

Date: June 11, 2013

Categories: Children / Discipleship

The New City Catechism was developed by Timothy Keller and Sam Shammas from the Reformation catechisms. It’s aim is to help teach and explain the building blocks of the gospel and to help strengthen the church’s distinct identity. It comprises 52 questions and answers—therefore there is only one question and answer for each week of the year.

New City Catechism is based on and adapted from Calvin’s Geneva Catechism, the Westminster Shorter and Larger Catechisms, and especially the Heidelberg Catechism.

It is divided into 3 parts to make it easier to learn in sections and to include some helpful divisions:
PART 1 = God, creation and fall, law (20 questions);
PART 2 = Christ, redemption, grace (15 questions);
PART 3 = Spirit, restoration, growing in grace (17 questions).

New City Catechism is a joint project between Redeemer Presbyterian Church and The Gospel Coalition.

The mobile friendly site I made:


The Christianado – New City Catechism made it onto a short list of four apps (not really because of the app itself, but because of the content). The other apps listed were the ESV Bible and content from R. C. Sproul and John Piper.  4 Actually Useful Spirtuality Apps, 31st October 2013.
