make a distinction among the persons of the Trinity, other terms have been used. One is subsistence. We are familiar with that term because it is often used to describe those who live beneath standard economic levels. A subsistence in the Godhead is a real difference but not an essential difference in the sense of a difference in being. Each person in the Trinity subsists or exists under the presence of deity. Subsistence is a difference within the scope of being, not a separate being or essence.
