Universalism is a theological and philosophical concept with universal application or applicability. Universalist doctrines consider all people in their formation. In terms of religion, in a broad sense, universalism claims that religion is a universal human quality. This can be contrasted with non-universalist religions.
Dualism, in religion, the doctrine that the world (or reality) consists of two basic, opposed, and irreducible principles that account for all that exists. It has played an important role in the history of thought and of religion.
