United Church of God
UCG believes that many laws in the Old Testament should be obeyed by Christians today, such as the Ten Commandments. They believe that certain foods such as pork and shellfish should not be eaten by Christians. They also believe the Holy Day festivals in the Old Testament should also be kept by Christians, including the "Days of Unleavened Bread", and the "Feast of Tabernacles". They also believe in observing the Sabbath on Saturday (from Friday sunset to Saturday sunset), and that Christians should not commit sexual sins. They do not believe in obeying the laws in the Old Testament about sacrifice, because they believe these laws were "fulfilled by the sacrifice of Christ."
