Biblically 3= complete; 7 equals perfection.
Complete perfection. Not about the trinity but about God Himself. 666 is about his arch enemy. One God , one arch enemy. One savior The Son of God and one gift of holy spirit we can receive.
They are not all the same. If God is Holy Spirit amd Jesus is God then whyndid he need to be baptized and have holy spirit descend upon him at a time when God said "this is my Son in whom I am well pleased". God isn't stupid He knows who His only begotten son is. Otherwise a good find.
Biblically 3= complete; 7 equals perfection.
Complete perfection. Not about the trinity about God Himself. It's becoming clear the trinity is bullshit propagated over 300 years after Christ came.
