Your unwillingness or inability to explain the origin of the Trinity is noted.
Jesus IS God, as God intersects our dimensional limits. That is what Jesus taught His disciples in the Upper room discourse the night bef9ore He was crucified. If you have trouble grasping that, let me know and I will expand upon it. It is the key to not only explaining the Trinitarian concept of God but also the way to comprehend how God can be a man and still be God, and simultaneously be The Holy Spirit and still be God. ‘Hear oh Israel, our God is One.’.
You've been shown examples from the Word which explains the Trinity.
The Father, Son and Holy Ghost have always existed. There is no origin point.
You're starting to sound more JW than catholic.
Your unwillingness or inability to explain the origin of the Trinity is noted.
I've never been asked. Let that be noted.
How can one explain something that never happened?
How is something "originated" that always has been?
I believe you will find the first mention of the Father, The Son, and The Holy Spirit in Genesis 1:26.
Nowhere in God's Holy Word is there any indication that God (all three parts) ever had a beginning.
God makes it clear that He has always existed.
So your statement quoted up above could be described as a straw man question, if it was phrased like that.
If you really have to have a beginning, check out Revelation 22:13
It's only the height or arrogance and pride that would enable anyone to even begin to THINK that they could "explain" the origin of the Trinity.
Puny, finite, mortal minds cannot grasp the unsearchable, infinite, and immortal.
By pride the Devil fell. God resists the proud and gives grace to the humble.
That Catholics think they can do it shows what spiritual danger they are in.
