Rome teaches contrary to your interpretation of Scripture, not contrary to Scripture itself.
"You may read the Bible from Genesis to Revelation, and you will not find a single line authorizing the sanctification of Sunday. The Scriptures enforce the religious observance of Saturday, a day which we never sanctify." Cardinal Gibbons (for many years head of the Catholic Church in America), The Faith of Our Fathers (92d ed., rev.; Baltimore: John Murphy Company), p.89.
