From Churchwatch Central:
For Reformation Day, we want Christians around the world to consider who they think are the most dangerous heretics in the world today undermining Christianity. The Pope will always be the most serious threat to Christianity since at the Council of Trent, the Roman Catholic Church anathematized the gospel.
In this article, we list our top 20 most dangerous heretics that Christians world-wide must mark and avoid (Romans 16:17) for the sake of Christ’s people and Christ’s gospel. We have also color-coded the heretics so people can identify what modern-day cult they represent.
