Why do Christians Worship on Sunday?

A reader, Jan, sent me this email:

I do have a query about Sundays. It seems to me that Peter still attended the Synagogue on the Sabbath in Acts 15:21. So, why and when did we decide that Sunday is set aside for Christ, rather than the Sabbath, or the seventh day of the week?

Many Christians and non-Christians alike have asked this question. After all, in Bible times the Jewish custom was, and still is today, to observe the Sabbath day on Saturday. We'll take a look at why a Saturday Sabbath is no longer observed by most Christian churches and attempt to answer the question, "Why do Christians worship on Sunday?"
