This Bible study investigates Babylon the Mother Church of Revelation. This Harlot Woman of Bible Prophecy also called the Beast is a Church claiming to be the mother of all modern day churches. The Bible accurately points to the Church of Rome as this great religious power and we will discover her claim as to actually have the ultimate Mark of ecclesiastical power and authority. This Mark we will discover is the counterfeit of the seal of God, which is the Seventh Day Sabbath. This information is vital to every sincere and searching Christian who is preparing for the last great conflict between Christ and Satan just before His glorious Second Coming. Please enjoy these sobering facts and consider their call to follow Jesus by faith in these last days. David Gilmore.
