Yes, there's universalism, but the fact that "Everyone is equal" is also embodied in most people's moral and philosophical codes in the first place. Not saying that's the main point of universalism.
Actually, universalism is the adknowledgement of a higher power (theism) without reprobation. That is, that all faiths can lead to the same path in "God's" eyes, even atheism, and there is no condemnation for believing in one god or gods in particular, only for leading an unjust and amoral life. Which, you know, is basically the doctrine of most "good" atheists (the ones that live by morality), and, if true, basically points to the fact that faith doesn't matter at all, and that your actions and thoughts dictate your worth in "God's" eyes.
