After the lengths God has gone to to provide for our salvation with the atonement, the death of Jesus on the cross, and then provide us with His very own God breathed, Holy Spirit inspired word, it’s the height of arrogance for people, denominations, or churches to come along and sit in judgment on it and claim that all He did is not good enough, that mere mortal man must add to it and change it to improve it.
If the sinless, holy, immortal God Himself cannot provide adequate means for salvation and growth, whatever possesses men to think that adding their own mortal, sin corrupted efforts can fill it out and it make it complete?
The deception runs deep with that kind of thinking and leaves people even more open to deception of Satan as they look for something else to adhere to.

It’s not a mere “denomination”. It’s the true faith. That being true, the accusation of “arrogance” is inapposite. Illogical.
Since you went there: Sole Fide, also, is not to be found in the Bible.
