Well done. It amazes me how those who follow the RCC can be so blind to what scripture really teaches.
When you assent to a system that calls for and fosters assent of faith to her teaching under the premise of her assured veracity, rather than the weight of Scriptural warrant being the basis for assurance of Truth, then all evidence must be made to support Rome. Scripture is a servant to do that for Rome, not her master.
And the logic behind the argument used to support this premise is perverse and nukes the church.
