There is a long-standing debate over Sunday and Saturday among Christ-followers, both Jewish and non-Jewish. The institution of Sunday in historical Christianity is a well-known fact and for many Christians, their very identity is tied to Sunday and what it means. It carries deep meaning and substance. On the other hand, there is an entire denomination of Christians, Seventh-Day Adventists who reject the idea of doing away with the biblical Sabbath in favor of Sunday. And thus the argument… And then there are Messianic Jews who are often caught in the middle of this battle.
