The only cross in all of history that was turned into an altar was the cross on which Jesus Christ died. It was a Roman cross. They nailed Him on it, and God, in His majesty and mystery, turned it into an altar. The Lamb who was dying in the mystery and wonder of God was turned into the Priest who offered Himself. No one else was a worthy offering.
