The Fifty Miracle Principles of A Course in Miracles®
by Kenneth Wapnick
 

Principle 40

The miracle acknowledges everyone as your brother and mine.  
It is a way of perceiving the universal mark of God.

The error that the miracle corrects is the error of believing that we are separate. Whether we are separated by our bodies or separated by the terrible things we believe people do, all the miracle does is reflect the fact that we are one, and that is what Jesus is always reminding us of -- that we are all one with him. The "universal mark of God" would be our sharing in the light of Christ.

Q: And it is sort of an inclusive system. No one is excluded.

A: No one is excluded. It could not be the Sonship if someone were excluded.
