True Christian Religion (written by Emanuel Swedenborg and translated in 1988 by John Chadwick), contains the complete theology of the New Church.
The faith of the New Heaven and the New Church in particular terms, set out in paragraph 3, is:
1 God is one, in whom is the Divine Trinity, and He is the Lord God the Saviour Jesus Christ.
2 Faith leading to salvation is believing in Him.
3 Evil actions must not be done because they are the work of the hells and come from the hells.
4 Good actions must be done because they are the work of God and come from Him.
5 A person must perform these actions as if they were his own, but he must believe they come from the Lord working in him and through him.
