I was trying to find the council that switched worship to Sunday but couldn't remember how to spell Laodicean. While looking I stumbled across this great page on the Sabbath in wikipedia http://en.wikipedia.org/wiki/Sabbath
I remembered it had to do with Christians trying to distance themselves from the Jews but couldn't remember when they did it.
"It is known that Gentile Christians sometimes openly observed the Biblical Sabbath in conjunction with first-day Sunday worship, because the Council of Laodicea [4] around 365 attempted to put a stop to the practice. Some conjecture, then, that prior to the Laodicean council Saturday was observed as a Sabbath and Sunday as a day of worship, primarily in Palestine; but after the Laodicean Council, resting on the Sabbath was forbidden. This is often considered an attempt of the early Christian church to distance itself from Judaism which had become unpopular in the Roman Empire after the Jewish-Roman wars, see also Constantine I and Christianity#Constantine and the Jews."
