McGee - The Sabbath is Saturday
J. Vernon McGee told of a man who came to him and said, “I’ll give you $100 if you will show me where the Sabbath day has been changed.” McGee answered, “I don’t think it has been changed. Saturday is Saturday, it is the seventh day of the week, and it is the Sabbath day. I realize our calendar has been adjusted, and can be off a few days, but we won’t even consider that point. The seventh day is still Saturday, and it is still the Sabbath day.” He got a gleam in his eye and said, “Then why don’t you keep the Sabbath day if it hasn’t been changed?” McGee answered, “The DAY hasn’t changed, but I have been changed. I’ve been given a new nature now, I am joined to Christ; I am a part of the new creation. We celebrate the first day because that is the day He rose from the grave.” That is what it means when we say that the ordinances have been nailed to the cross, Col. 2:14. (Source unknown).
