Great is the authority of the Church
You will have noticed, my dear children, that the day on which we keep the Sabbath is not the same as that on which it was observed by the Jews. They kept and still keep the Sabbath upon Saturday, we upon Sunday; they on the seventh day, we on the first day of the week. Hence the Jews close their shops and attend their synagogues upon Saturday, but Sunday is observed as the day of rest by all Christians, even by those sects who are separated from the Catholic Church. You will ask, what is the reason of this? It is because the Apostles, who were the first pastors of the Church, by the authority which [p. 107] they had received from our Blessed Lord to regulate all that regards his public worship, changed the day appointed for the keeping of the Sabbath from Saturday to Sunday from the seventh to the first day of the week. And why did they do so? To honour the glorious Resurrection of our Lord and the Descent of the Holy Ghost upon the Apostles, both of which mysteries were accomplished on the first day of the week. From this we may understand how great is the authority of the Church in interpreting or explaining to us the commandments of God an authority which is acknowledged by the universal practice of the whole Christian world, even of those sects who profess to take the Holy Scriptures as their sole rule of faith, since they observe as the day of rest not the seventh day of the week commanded by the Bible, but the first day, which we know is to be kept holy, only from the tradition and teaching of the Catholic Church.

Herder Book Co, 15 and 17 South Broadway, St. Louis, Mo., and London, W. C. 33 Queen Square, in 1937, Twelfth Edition, page 50.
... in 336 A.D., the Catholic Church, at the Council of Laodicea, made the ecclesiastical law obliging the faithful to attend Mass and to abstain from servile works on Sundays. And all Christians accepted that law in virtue of the divine authority Christ gave to His Church when He said, "Whatsoever you bind upon earth shall be bound also in Heaven; and whatsoever you loose upon earth shall be loosed also in Heaven" (Matt., xviii, 18).
What does all this mean? It means that the Seventh Day Adventists are wrong in saying that the Jewish Sabbath still obliges, for there is clear authority in the Bible for its abrogation.
Seventh Day Adventists are right, however, in accusing other Protestants of inconsistency who speak of any obligation of Sunday observance whilst rejecting the authority of the Catholic Church. It is not that there is no authority in the Bible for Sunday observance. But there is no direct authority for it as an obligation. The only direct authority for it is that of the Catholic Church; but that involves the authority of the Bible at least indirectly in so far as the Bible itself teaches clearly that the Catholic Church is directly authorized by Christ to legislate in His name.
