Universalism became a significant minority view in the 18th century, popularized by thinkers such as John Murray (the American, not the Scot). Universalism holds that Christ's death on the cross has entirely atoned for the sin of humanity; hence, God's wrath is or will be satisfied for all people. Conservative and liberal varieties of universalism then point in different directions. Pluralistic Unitarian Universalism asserts that many different religions all lead to God. Others teach that God's love is sufficient to cover for sins, thus embracing some form of the moral influence theory of Peter Abelard. For some universalists, justification either was accomplished once and for all in the crucifixion, or is altogether unnecessary.
