In 1980 I was stationed at Kunsan Air Base in South Korea. While there I heard a Baptist preacher tell a group in Bible study that “all roads lead to Rome” meaning every religion can get you to heaven. I was a new believer, but I knew this was wrong! I challenged him, because NO ONE else would say a word. He was a popular preacher and I was a new convert so you can imagine whose side everyone lined up on. My point is this, when you hear false preaching or teaching SAY SOMETHING! The Apostle Paul was the new kid on the block (Read Galatians) yet he challenged and corrected the Chief Apostle Peter for treating the Gentile believers wrong.
Ministers are NOT infallible, only the Word of God is! No matter how popular or how powerful a preacher is, they are NOT above reproach!
