Is it a sin to worship on Sunday instead of Saturday

I have posted a couple of times about worship on Sunday. It can be a hot topic among Christians.

Some Christians believe that the Sabbath is Saturday and that as one of the ten commandments, God has commanded that Saturday be our day of worship. Any other day is a compromise on God's commandmants and thus a sin.

Other Christians hold that the church moved the Sabbath day from Saturday to Sunday to recognize the day of Christ's resurrection as our day of worship.

Still some Christians don't hold to any particular day at all and many may not even feel that any day is required.

Personally, I fall into the Sunday camp. John Piper gives a great sermon explaining this point of view. I believe God still expects us to take a day of rest but that this rest now illustrates the rest achieved from Jesus' resurrection as opposed to the rest from creation. Pastor Piper cites John 5:17 as showing that God was no longer in the rest he declared after salvation but has started the work of redemption. With the death and resurrection of Jesus we have now entered and begun (but not completed) our final rest (Hebrews 4:9-10).

On my previous two posts I had a great contributer that takes the opposite view. Banner Kidd believes that God still holds the Sabbath as Saturday and the church has changed this law for their own purposes or conveniences.

See his comments to my posts "Saturday, Sunday, or any day" and "Has grace replaced the ten commandments".

You may agree with one of these views or you may have a completely different opinion. That's the point of this discussion post.

Remember, this is a discussion post and all opinions are welcome. However, I will use my moderators prerogative to delete any comments I deem as hateful or spam.
