Constantine as Emperor was the head of the Roman religion.
He had the Pagan title of Pontifex Maximus, the high priest leading
those who died over the bridge to haSatan.He called the Council at Nicea,
he presided over it and
he promulgated the results to the Empire.Which is quoted in # 839 above.
He was never a follower of the Christ.
Some believe that he may have been baptized
by a heretic on his death bed.He ordered the celebration of Easter, a Pagan feast
and the prohibition of celebrating of Passover and First Fruits
which were celebrated by Yah'shua as the "last Passover"
and the day he rose from the dead.
