Vatican Statements on the Sabbath:
“Sunday – fulfillment of the Sabbath. Sunday is expressly distinguished from the Sabbath which it follows chronologically every week; for Christians its ceremonial observance replaces that of the Sabbath… “
“The Sabbath, which represented the completion of the first creation, has been replaced by Sunday which recalls the new creation, has been replaced by Sunday which recalls the new creation inaugurated by the Resurrection of Christ…”
“In respecting religious liberty and the common good of all, Christians should seek recognition of Sundays and the Church’s holy days as legal holidays.”
“2177 The Sunday celebration of the Lord’s Day and his Eucharist is at the heart of the Church’s life.
"Sunday is the day on which the paschal mystery is celebrated in light of the apostolic tradition and is to be observed as the foremost holy day of obligation in the universal Church."110”
"Also to be observed are the day of the Nativity of Our Lord Jesus Christ,
the Epiphany,
the Ascension of Christ,
the feast of the Body and Blood of Christi,
the feast of Mary the Mother of God,
her Immaculate Conception,
her Assumption,
the feast of Saint Joseph,
the feast of the Apostles Saints Peter and Paul, and the feast of All Saints."111”
“The Sunday obligation”
“2180 The precept of the Church specifies the law of the Lord more precisely: "On Sundays and other holy days of obligation the faithful are bound to participate in the Mass."117 "The precept of participating in the Mass is satisfied by assistance at a Mass which is celebrated anywhere in a Catholic rite either on the holy day or on the evening of the preceding day."118”

“The present canonical and liturgical provisions allow each Episcopal Conference, because of particular circumstances in one country or another, to reduce the list of Holy Days of obligation. Any decision in this regard needs to receive the special approval of the Apostolic See, (127) and in such cases the celebration of a mystery of the Lord, such as the Epiphany, the Ascension or the Solemnity of the Body and Blood of Christ, must be transferred to Sunday, in accordance with liturgical norms, so that the faithful are not denied the chance to meditate upon the mystery. (128) Pastors should also take care to encourage the faithful to attend Mass on other important feast-days celebrated during the week. (129)”

Cardinal James Gibbons, The Faith of Our Fathers
Third–A rule of faith, or a competent guide to heaven, must be able to instruct in all the truths necessary for salvation. Now the Scriptures alone do not contain all the truths which a Christian is bound to believe, nor do they explicitly enjoin all the duties which he is obliged to practice. Not to mention other examples, is not every Christian obliged to sanctify Sunday and to abstain on that day from unnecessary servile work? Is not the observance of this law among the most prominent of our sacred duties? But 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.

[pg. 174]
Q. Have you any other way of proving that the Church has power to institute festivals of precept?
A. Had she not such power, she could not have done that in which all modern religionists agree with her;—she could not have substituted the observance of Sunday the first day of the week, for the observance of Saturday the seventh day, a change for which there is no Scriptural authority.
Q. Has the Church power to appoint days of fasting?
A. Certainly; for St. Augustine, one of the bishops of the early and confessedly pure Church, taxed Aerius with heresy, for having disputed that right.
Q. Can the Church forbid us the use of certain kinds of food on particular days?
A. Yes; for she did so even in the time of the Apostles, Acts xv, 29—“That you abstain from things sacrificed to idols, and from blood, and from things strangled.”

It’s really difficult via a forum to cut down the vast amount of Vatican documents from its own libraries that show the world is fully submitted to her. I believe that this is true beyond any doubt and unity/submission will continue worldwide at an accelerated rate.
