I recall a rather simplistic explanation once that stuck.
As a man, you are a father to your , son. A son to your father. A husband to your wife. A friend to your friends.. God's nature has many aspects, but that doesn't mean He is many gods. I remember how the Israelites had many names for God Iehouah (Jireh, Rapha, Nissi) which described different attributes. Just because they placed different names to describe different attributes, it doesn't describe three separate Gods.
I wonder how the Israelite descriptive names can be attributed to the Trinity's attributes?
Jireh: The Lord Who Provides
Rapha: The Lord Who Heals
Nissi: The Lord Our Banner
Just typing to ‘think out loud’ for now.
Those names remind me of the Archangels:
Michael — the one who protects.
Raphael — the one who heals.
Gabriel — the one who brings messages.
There are many more, but those are the ones we have names for from the Bible.
The different names for God are very interesting. Never quite thought of it that way.
