So was the Roman Catholic Church as it was preempted by Constantine in the 300's. Roman holy days were used for many of the Christian holy days we celebrate today.
And celebrating a holy day on day "n" has what to do with salvation?
For as much as some protestants complain about legalism, complaining about the date of a celebration is about as legalistic as you can get. Perhaps we shouldn't be cooking on Sundays either.
