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.
Open theism. Open theism, also called free will theism and openness theology, is the belief that God does not exercise meticulous control of the universe but leaves it open for humans to make significant choices (free will) that impact their relationships with God and others. A corollary of this is that God has not predetermined the future.
