The Catechism in Questions & Answers

749. How is the relationship of the New Apostolic Church with other churches, denominations, and religions?

The New Apostolic Church and its members respect the religious practices of other people and refrain from making derogatory remarks concerning those of different faiths, different religions, and different denominations. They endeavour to have a good and peaceable relationship on the basis of mutual respect. The Church rejects all forms of religious fanaticism.
In dialogue with other Christian churches—irrespective of differing doctrinal positions—the commonalities of the Christian faith are emphasised.
