Lindsey Medenwaldt and Melissa Dougherty deceptively try to explain away passages in the Bible that reveal the Earth is flat and stationary. They base their arguments on the premise that the Bible is not a science book and thus statements about God’s creation of a flat and stationary earth cannot be taken literally. That is the stratagem used throughout the ages to undermine the gospel.

One might think I am being unkind to call them “dingbats.” But I base that epithet on what Jesus calls those who preach a false gospel. <...> Jesus called the scribes and Pharisees who taught false doctrine “fools and blind.” Matthew 23:17.

The active opposition of false ministers of the gospel exposes them as antichrist disciples of the devil. Such persons are quite different from those who are ignorant about some truth in the gospel. A person is not against Christ if he simply does not know about God’s creation of a flat earth but otherwise supports the truth of the gospel as far as he knows.

Those who attack the biblical account of God’s creation of a flat and stationary earth are enemies of the gospel of Jesus Christ. It is not a matter of ignorance. They are in an active campaign against the word of God.

If men have a misunderstanding of God’s creation, they will also have a misunderstanding of who God is. If people believe in a creation that does not exist, they consequently also believe in a creator that does not exist. It is essential, therefore, to have an accurate understanding of God’s creation. God did not make a movable, spherical earth. If men believe in a heliocentric creation, they will necessarily believe in a heliocentric creator. A heliocentric creation does not exist. So also, a heliocentric creator does not exist. A heliocentric creator is a false god. We have been warned to avoid the preaching of a false gospel, which presents a false Jesus.
