I didn’t make it myself. I found it on a website. I was surprised to see that I instantly agreed with most of it.
Somebody did question me on it when I shared it elsewhere. They asked me “What about the Ethiopian Orthodox?” and I had to think about it.
If I made this chart, I would put the Oriental Orthodox and Eastern Orthodox on parallel lines. I don’t know how I would place Islam as I believe there are a number of movements within peoples who refer to themselves as Islamic, some of which are accurately Islam and some of whom stray from it but still use the name.
But I lack some knowledge in that area.
