When was day of Christian worship changed from Satruday to Sunday?

A: There is in fact no Scriptural mandate or confirmation for the change of Christian worship from Saturday to Sunday. There is some evidence that ancient Christians did consider the First Day of the Week "the Lord¡¦s Day"¨ in commemoration of the resurrection, but this does not constitute a "replacement" of the Sabbath. The earliest decree I know of proclaiming that Sunday should be observed instead of Saturday is the Council of Laodicea, (364 AD ):

Canon 29: "Christians shall not Judaize and be idle on Saturday, but shall work on that day; but the Lord's day they shall especially honor, and, as being Christians, shall, if possible, do no work on that day. If, however, they are found Judaizing, that shall be shut out from Christ."

Similar rules appear in subsequent regional councils. The very fact that the Roman church found it necessary to make such rules is however evidence that Christians were observing the seventh day. There is, in fact, abundant testimony that many early Christians did observe the Sabbath. Some apparently observed both.

The Laodicea 29 rule is invalid, of course. The apostle Paul specifically tells us not to make an issue of Sabbaths and special days. (Colossians 2:16, Galatians 4:10, 11). The church has no business making such a rule. By the same token, churches which meet on Sunday are committing no sin in so doing.
