O wow. Now there is an assertion.
God Exists
Is not an assertion unique to Christianity therefore is not a valid distinction.
Jesus Christ is God
Is an inaccurate simplification of the Trinity. And the Trinity is not a definitive doctrine for Christianity. Restoration (if it exists) does not rely on a divine Christ.
The Bible is divinely inspired
Depends very much on your definition of “Inspired”. Which is the source of many disagreements even within the Catholic faith let alone outside of it.
The Bible explicitly condemns discord ff
Your Scriptural proof is flawed. It relies on a specific view of dissension, and faction, especially as to who we are disagreeing with. There are faction within Catholicism ,let alone describing other denomination as such.
And this has been one of you hobby horses (along with abortion)
You cannot claim a single view, let alone that you have it. That is not the understanding of discord or division. You can agree to differ in belief and still have both accord and unity.
