For Catholics tradition trumps Scripture.
We’ve shown them time and again verses from Scripture that demonstrate that sola Scriptura has a Scriptural base but they simply do not believe that the God breathed, Holy Spirit inspired word of God is adequate.
They’ve fallen for the lie that Satan trapped Eve with. *Did God REALLY say.....?*
Impugning the Word of God is the only weapon the enemy has and it’s amazing that He is still getting mileage out of it even today.
There is no convincing someone who doesn’t think Scripture is enough. They are so far in the depths of deception that without the Holy Spirit opening their eyes, there’s no hope for them.
But they can't even prove today's "traditions" are the same traditions the apostles were talking about.
