Alright. Here's one. It is. It's 3 gods. They may be the same, but they are also different. God does appear this way.

 We can cite the catholic art of the 1st millennium. Where they have these 3-god dictates. I don't know why I ever doubted it. My ultimate lesson & experience, however, is that God does this to interact with Creation. The Holy Ghost, for example, is God as a Martyr. Well, he does inherently surpass all known or could-be-given limitations.
