Yes, you should become a Catholic, or at least attend their Church, and then spread the truth anytime you can of what the truth of the scriptures state, until they boot you out of their Church, but it was well worth it.
Like Paul that went in to the Jewish synagogues, and preached the truth of Jesus.
I think it would be neat if all the Protestants started going to Catholic Churches, every Protestant, and preach, and preach the truth, and the chaos we could put upon them as we go to their mass, and go to their Bible studies, and proclaim the truth until they are at their wits end, and the assembly in an uproar not knowing what to believe, and doubting the Catholic faith.
But then again it might not be such a good idea, for the Protestants might make them mad, and the Pope and Vatican call for persecution of those who oppose them to be enforced again, and here we go again.
