While traveling, Paul and his companions made a concerted effort to gather with local believers in the first day of the week to break bread. While this doesn’t necessarily set a precedent for a Sunday church service, it at least explains why many Christians now meet on Sunday. If this verse is to be used to support a Sunday church service, then it should probably be used to emphasize the importance of the Lord’s Supper, or communion, during that gathering.
What do you think? Does the context support these ideas?
