The Sabbath and Sunday worship: While the Sabbath, observed on Saturday, finds its origins in the biblical commandment, Sunday worship holds significance in Christianity. The Sabbath, rooted in Creation, is a day of rest, reflection, and worship for Jews and some Christian denominations. Jesus upheld the Sabbath's importance, emphasizing its purpose for humanity. Gradually, Sunday, the day of Jesus' resurrection, gained prominence as a time for corporate worship among early Christians, especially Gentile converts. Various historical and theological factors influenced the transition from Sabbath to Sunday worship. Today, different Christian denominations observe Sunday as the primary day for communal worship, celebrating the Lord's Day. It's important to respect both traditions, recognizing their significance and fostering understanding among diverse religious practices.
