I’ve heard Augustine quoted as saying that if you deny the Trinity you could lose your soul and if you try to explain it you could lose your mind. Along the lines of the latter have come various diagrams to try to help us understand the Trinity. Justin Taylor recently posted a diagram which looks like this:
This is a variation a simpler diagram which looks like this:
Taylor’s diagram adds a few elements which try to draw out the doctrine of perichoresis and the fact that the persons of the Trinity all work to glorify each other. I found another diagram which adds yet a couple of other elements.
This adds the doctrine of the begetting of the Son and the procession of the Spirit and the mutual love of the persons for each other. This diagram does not represent the filioque (which says the Spirit proceeds from the Father and the Son). Diagrams have also been used to illustrate false views of the Trinity.
Do you find diagrams such as these helpful? I do. Do you have a favorite?
