Moses? or Christ

Did Israel have Christ? Or did Israel have another way of finding approval with God? Is the church a completely different order than Israel? What is the relationship between Israel and the Church? What about Moses and Christ? Does Christ have nothing to do with Moses? The danger is on the right hand or on the left. Some would turn grace into law, turn the church into Israel, and Christ into Moses. Others would deny Christ to Israel and make Moses a savior, and law into grace. The error on the one hand is to make no difference between law and grace; the other error is to see nothing of Christ in Moses.
