If this is the case, the next step in the proposal email would be the go-ahead for you to create the letter of agreement. I'll discuss those in a future post. As with all business emails, make every sentence as concise as possible. Avoid jargon and biz-blab.
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.
(Theism: Longer definition) Theism states that the existence and continuance of the universe is owed to one supreme Being, who is distinct from Creation. For this reason, theism proclaims a dualistic relation between God and the world, wherein God is a being who controls events from outside of the human world. The main question theism raises is whether God should be seen only as transcendent, that is, beyond the limits of human experience and the material world.
