Another step to bringing clarity to the issue of what the Trinity is not.
This has to do with the essence of God. When we talk about God’s essence, we are speaking of the “stuff” that God is made up of (not made of!). It is often referred to in philosophical language as the “ontos” of God. In the fourth century, at the Council of Nicea, this was referred to as the “ousia” as Christ was declared to be of the same ouisa (homo-ousia), rather than sharing an essence that is merely like or similar to the Father. Christ shares in the exact same ousia, ontos, essence, or “stuff” as the father.
It is important to note that this sharing is an absolute unity (God is one), so as to avoid the temptation to divide the same ontos into three parts. In other words, this is not what the Trinity is:
Notice the difference from what I posted yesterday.
See the difference? I cannot overstate how important this is. The first chart is tritheism. The second is Trinitarianism.
