A former Jesuit priest, Alberto Rivera was introduced to the world through the ministry of Gospel tract publisher Jack Chick. Rivera’s incredible testimony can be found in the Alberto series of comic tracts produced by Chick Publications. Videos of some of his sermons are below.

DISCLAIMER: Both Jack Chick and Alberto Rivera were Seventh Day Adventists. The Seventh Day Adventists claim to be a Protestant denomination, but many of their doctrines, such as the Rapture, are not biblical. The book, The Great Controversy, written by Ellen White, the organizations founder, is required reading for all Adventists, and is quoted more often than the Bible. Notwithstanding, Rivera’s testimony gives much insight into the nature, beliefs, and goals of the Roman Catholic Church; and is therefore of great value.
