We do know that churches in the NT came together to discuss doctrine and voted on the same. If you don’t want to call that a denomination, well, I don’t know what it would be.
But GOD; did not ordain that .. the MEN in the NT churches did that.
At the time the “churches” were created .. Jesus was not around. All they had was HIS WORD. However, there are chapters in the Bible about how to organize a church (I think it might be in Timothy); it was Paul who was teaching how to organize their groups. Still, I’ve never read anything about any denomination rules; Catholic vs Protestant.
