Pope calls for Sunday Sacredness as a day of rest

“A message of hope went out from Milan to the whole world,” Pope Benedict XVI told his regular weekly public audience on June 6, as he recalled his visit to that Italian city last weekend for the 7th World Meeting of Families.
During his encounters with the participants in the World Meeting of Families, the Pope said that he had been repeatedly struck by the reports of families facing challenges because of economic difficulties, divorce, and other problems. He focused especially on one particular challenge: the need to set aside the Sabbath (meaning Sunday) for worship and family time. The Pope told his audience:

I wish to recall what I have often said in the past in defense of family time, which is threatened by the imposition of work-related commitments. Sunday is the day of the Lord, the day of man, a day in which everyone must be free, free for the family and free for God. By defending Sunday we defend man's freedom." CatholicCulture.org

But Sunday isn't Sabbath-Saturday is....the 7th day...
But the seventh day is the sabbath of the LORD thy God:
