While beliefs can differ on the nature of ultimate reality based on personal experience and interpretation, the consistency of the similar quality of being should tend to unite people as they mature in their individual faiths—

As truth is encompassing, universality of knowledge is a function of enlightenment... In the same way scientific laws are consistent throughout the universe, so are spiritual truths. Peoples of faith in the universe, to the extent they honestly seek truth, will gravitate toward universal spiritual laws, tending to unite on at least the basics.

These would be recognized as consistent based on the goodness and quality of life.
