Don't judge them, Petronski. They think they're doing good. Our job is not to argue or debate the Truth. The Truth is what it is -- the Faith as handed down to us by two thousand years of Tradition. Our job is to present that Truth, and to lovingly correct any errors of fact that may be propagated as truth. That being done, it's counterproductive to say more. Instead, let's pray for them. They need it. Imagine the burden of being your own personal Pope, on duty 24/7, a "church" of one, dependent solely upon one's own personal interpretation of King James' version of the Scripture that our Church gave them for comfort. No saints, no Mary, just themselves and a book of printed pages. How lonely and sad. Talk about a hell on earth!
The Protestant Heresy is almost dead. Like Arianism, it had its day, but it was always a house built upon sand. The Anglicans/Episcopalians are gone; the Presbyterians, Methodists, and Lutherans are going; and even the Baptists are crumbling, worn away by the flow of modernism and the corrosion of individual religion. As for the Evangelicals, the good and true among them are slowly but surely returning to the Church. The rest will continue to self-interpret and Pharisee along until the social structures that support them collapse. Then, with the wolves at the gates, they too will rush to the doors of St. Peter -- and those doors will open.
When it all comes rumbling down, the Church will be here. As BlackElk once said, "the Catholic Church has shoveled two thousand years of dirt upon the faces of its enemies"; the heresy of Martin Luther and John Calvin, and the self-centered hedonism of the Evangelical movement, are only the latest two bodies to bury. Heresy and schism comes and goes; the true Church abides.
