Augsburg Confession Admits.....

But the seventh day is the sabbath of the LORD thy God: Exodus 20:10

The Augsburg Confession:

"They [the Catholics] allege the Sabbath changed into Sunday, the
Lord's day, contrary to the decalogue, as it appears; neither is there any example more boasted of than the changing of the Sabbath day. Great, they say, is the power and authority of the church, since it dispensed with one of the ten commandments."
