I understand, but it's just terminology...I had just never seen such a clear chart of the Roman denomination variations.

It's not terminology. These churches all have exactly the same beliefs, unlike Protestant denominations. The only differences are forms of the Mass and some canon law (church administration).

Sorry, but most Protestant churches share core theological beliefs.
