I have been surfing the web and came across a church group that believes the resurrection was on the Sabbath (Saturday) and that worship of Jesus or His resurrection on Sunday, or any other day, is sinfully wrong and can be a determining factor in salvation. Please help me with this!
This church's claim that corporate "worship of Jesus [on any day other than Saturday] is a sinfully wrong" is a false teaching without any biblical support. And their claim that the day on which we gather to worship has a determining factor in our salvation is both sad and heretical. There is no biblical support for such a belief and it is contrary to the gospel message of freedom and rest found in Christ. Plus, most significantly, it adds a work that we can perform to the finished work of Jesus on the cross that atones for our sins and liberates us from bondage to sin. Our salvation is a free gift, unmerited and unearned by us, determined only by the Lord's goodness, mercy and grace. Salvation is not dependent upon our day of worship or anything we can do. It is received by us when we repent and trust in Jesus' finished work upon the cross for the forgiveness of our sins.
Certainly we should gather to worship Jesus, but it can be done on any day of the week. The Bible is clear about God's instructions to the Nation of Israel. They were to keep seventh day of the week, Saturday, as the Sabbath day of rest (Exodus 20:8, Deuteronomy 5:12). We are not the Nation of Israel. We are the Body of Christ, the Church, and we live under the New Covenant that was established with the death, burial and resurrection of Jesus. Our Sabbath rest is not found on a designated day, but rather our Sabbath is found in a designated Person ... the Lord Jesus Christ (Hebrews 4). Because our Sabbath rest is found in Jesus—and Sabbath is every day of the week. It is a continual rest, that is without ceasing. We abide and we rest in the richness of the gifts that He has given us. Our rest is in knowing we have eternal life with Jesus and our rest is in surrendering to the power of the indwelling Holy Spirit who teaches and guides us.
Gathering for fellowship and corporate worship can be any day of the week. Therefore, Sunday is a perfectly acceptable day of worship. It should be noted that the apostolic church of the first century, which formed immediately after Jesus’ death, met on Sunday, the first day of the week (Acts 20:7). Sunday has been the traditional day for Christian worship since that time.
