The Catechism in Questions & Answers

38. How did the New Apostolic Creed come into being?

The New Apostolic Creed is the result of the Apostles’ interpretation of Holy Scripture and the early church creeds. In terms of content and language, its present form has come into being in line with ongoing developments in doctrine and deepening knowledge. It was formulated in the awareness that God’s love, grace, and omnipotence cannot be exhaustively described. These will always be greater than anything human beings can ever say about them. Thus the creed does not draw any boundaries that would deny other Christians access to salvation.
