According to the book of Genesis, when God created the world, he did so in six days. By the power of his Word he called into existence everything that exists, aside from God himself. Then, on the seventh day, God rested. Even before sin entered the world, God commanded his people to rest on the seventh day of each week. He created a weekly holiday so people would have a break from their usual work and would have time to celebrate fellowship with God and with each other.
In the Ten Commandments, God reaffirmed this commandment to rest on the seventh day of the week. Through the prophets he repeated the message that his Sabbath Day was to be respected. God never told any of the prophets that he was going to change his mind about that commandment (although he did reveal to Jeremiah that a new covenant was coming). Jesus debated with his opponents about the meaning of the Sabbath Day, saying that it was appropriate to do good and helpful things on that day. But Jesus did not signal that he was going to change God’s weekly holiday.
The vast majority of Christians in the world today worship God on Sunday. Sunday morning is treated as the weekly anniversary of the resurrection of Jesus. Christians are free to move their time of rest and worship from Saturday to Sunday, or to Wednesday night, or any other time they please. The apostle Paul wrote to the Colossians, “Let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath. These are a shadow of the things to come, but the substance belongs to Christ.” Kosher rules no longer apply, because they were related to the animals sacrificed on the altar, and Jesus has fulfilled the substance of which they were a picture. Christians are free to hold a Seder and observe the Passover week if they wish, but most choose instead to celebrate Holy Week and Easter, since Jesus has fulfilled the substance of which Passover is a picture. Christians do not have to make a Sabbath rest every Saturday, because Jesus has fulfilled the substance of which the Sabbath is a picture.
In the week of creation, God rested on the seventh day. In Holy Week once again, God rested on the seventh day. The body of the Son of God rested the rest of death, buried in a borrowed tomb. The soul of the Son of God rested in Paradise, in the hands of his Father. Whenever a Christian dies, that Christian rests the same way—the body buried or otherwise resting on earth, the soul with Jesus in Paradise.
But the rest of Jesus was short. When the Sabbath ended, a new day began, and Jesus no longer rested. The substance of the Sabbath was fulfilled, as the substance of Passover and of animal sacrifices was fulfilled in the death of Jesus. Christians are free, not only from sin and death, but also from the burden of the Law. “Let no one pass judgment on you,” for God has already judged you worthy of eternal life in his Kingdom. J.
