I don't think they can even do that. Roman catholicism didn't come into existence until the 4th century. The NT canon was established well prior to that. I'll give 'em Trent when they officially made their canon.
The writing of the Scripture is the work of the Holy Spirit and we would know about Jesus because GOD made sure we would not because the Catholic church made sure we would.
He sure seemed to do ok in getting the OT put together without roman catholicism didn't He!
God can do just fine without the Catholic church.
And He will continue to do fine in spite of it.
Just like He's always been doing.
There are churches in heavily Catholic areas that are just chock full of former Catholics.
