Constantine’s Cross
Constantine claimed to have seen a cross in the sky with the words: IN HOC SIGNO VINCES or IN THIS SIGN CONQUER.
The cross and the words IN HOC SIGNO VINCES or IHS became the battle standard of the Papal Roman Empire.
Constantine’s division of the Empire into 2 halves was the fulfillment of King Nebuchadnezzar’s dream in Daniel chapter 2
