Yahshammah, not only did Christians murder their opposition (The Crusades, The Inquisition), and back Hitler in WWII, but they "Changed the Times and Laws" that the Bible warns about.
Daniel 7:25 And he (The BEAST) shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time.
The Roman Beast has changed the 24 hour day from sunset to sunset to the midnight hour of witches. They changed YHVH's calendar first to the Julian (Julius Caesar) calendar, and now the Gregorian (Pope Gregory) calendar. They changed YHVH's International dateline from jerusalem to the middle of the Pacific Ocean. And ALL Christians claim that The Laws of The Covenant (Torah or ten Commandments) were nailed on the cross, but that is just not true. The Laws have merely been revealed as LAWS of LOVE (Made replete or fulfilled). So the real answer to the real question is. How do we know that Christianity is a cult? and the answers are already stated by Yahshammah, Matthew 24, and me.
