So, for example, if "the Roman Catholic" rejects what the sola scriptura crowd says, according to the grace of God, the sola scriptura crowd gets to judge the RC? I'm just trying to figure out what you're saying. That GOD is going to have the sola scriptura crowd judge the RCs that do not reject their own church?
God will do the judging of those who have rejected His words for the traditions of men (Mk.7:7-9) and they will be judged at the Great White Throne Judgement. (Rev.20)
You and your Roman Catholic friends have been informed of the truth, what you do with it is between you and the Lord. (Acts.13:51, Titus 3:10)
What we Catholics do with the truth is, collectively, operate and worship in the Church founded by Christ, lead by His Vicar on earth, Pope Benedict XVI, successor to St. Peter.
