The Church of God teaches that the Old Testament law of Passover is important. It claims that the Last Supper that Jesus had with his disciples was the same day as Passover, and so it celebrates Passover every year on the evening of January 14th of the Jewish calendar, with the breaking of bread and the drinking of wine. However, Passover as taught by the Church of God is not a biblical teaching. The link below is a refutation of Passover as taught by the Church of God.
