"Being a Christian is a process of continuing forward in faithfulness to Jesus from that point on. In order to make this commitment to Jesus, you need to know the essentials about who he is and what he has done for you."
-The Revd. Dr. James I. Packer, To Be A Christian: An Anglican Catechism (2020)
A "Catechism" is a manual for Christian teaching, outlining the faith in a simple and easy to understand question & answer format. Typically used to teach people preparing to receive Confirmation or who are new to the faith.
