10 Reasons Christians are NOT required to observe the Sabbath
1. Although a day of rest and worship is demonstrated by God in the creation, the Saturday Sabbath was given to Israel as the sign of the Mosaic Covenant (Ex 31:16-17, Ez 20:12, Neh 9:14). Since Christians are under the New Covenant (2 Cor 3:6, Heb 8), they are not required to observe the sign associated with the Mosaic Covenant.
2. There is no command in the NT for Christians to observe the Sabbath.
3. Even during the Mosaic economy, the OT neither commanded the Gentile nations to observe the Sabbath nor condemned them for failing to do so. That offers further proof that the Sabbath was given to Israel only.
4. There is no record in the Bible of anyone’s observing the Sabbath before the time of Moses. The first command to keep the Sabbath appears in the law given to Moses at Sinai (Ex 20:8).
5. The Jerusalem Council (Acts 15) did not impose Sabbath keeping on the Gentile believers.
6. The Apostle Paul warned the Gentiles about many different sins in his epistles but never about breaking the Sabbath.
7. Colossians 2:16-17 describes the Sabbath as a shadow of Christ; the shadow is no longer binding on us since the substance (Christ) has come.
8. In Galatians 4:10-11, Paul rebukes the Galatians for thinking that God expected them to observe special days, such as the Sabbath.
9. Romans 14:5 declares observing the Sabbath to be a personal preference among converted Jews. It was to be tolerated until they become more mature in the understanding of their Christian liberty. Therefore, it could not be something God requires believers to do.
10. The book of Acts and the subsequent writings of the early church Fathers make clear that the church from earliest times met for worship on Sunday.
