John Paul's letter, Dies Domini, goes to great lengths trying to justify, from Scripture, the change of the Sabbath to Sunday. It's not the Sabbath that has changed, however, but the position of the church regarding the change.

Let's let honest Catholics speak for themselves about who really changed the Sabbath.
