Here are a few statements from "your" church fathers...
“Nowhere in the Bible is it stated that worship should be changed from Saturday to Sunday...Now the Church...instituted, by God’s authority, Sunday as the day of worship. This same Church, by the same divine authority, taught the doctrine of Purgatory long before the Bible was made. We have, therefore, the same authority for Purgatory as we have for Sunday.” Martin J. Scott, Things Catholics Are Asked About, 1927 edition, p. 136.
“Question - Which is the Sabbath day?
“Answer - Saturday is the Sabbath day.
“Question - Why do we observe Sunday instead of Saturday?
“Answer - We observe Sunday instead of Saturday because the Catholic Church, in the Council of Laodicea (A.D. 364), transferred the solemnity from Saturday to Sunday.” Peter Geiermann, C.S.S.R., The Convert’s Catechism of Catholic Doctrine, p. 50, 3rd edition, 1957.
“Question: How prove you that the church had power to command feasts and holydays?
“Answer: By the very act of changing the Sabbath into Sunday, which Protestants allow of and therefore they fondly contradict themselves by keeping Sunday strictly, and breaking most other feasts commanded by the same church.
“Question: Have you any other way of proving that the church has power to institute festivals of precept?
“Answer: Had she not such power, she could not a 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 of the week, a change for which there is no Scriptural authority.” Stephen Keenan, A Doctrinal Catechism On the Obedience Due to the Church, 3rd edition, Chapter 2, p. 174 (Imprimatur, John Cardinal McCloskey, Archbishop of New York).
“Question. - How prove you that the Church hath power to command feasts and holy days?
“Answer. - By the very act of changing Sabbath into Sunday which Protestants allow of; and therefore they fondly contradict themselves, by keeping Sunday strictly, and breaking most other feasts commanded by the same Church.
“Question. - How prove you that?
“Answer. - Because by keeping Sunday, they acknowledge the Church’s power to ordain feasts, and to command them under sin: and by not keeping the rest by her commanded, they again deny, in fact, the same power.” An Abridgment of the Christian Doctrine, composed by Henry Tuberville, p. 58.
“Some theologians have held that God likewise directly determined the Sunday as the day of worship in the New Law, that He Himself has explicitly substituted the Sunday for the Sabbath. But this theory is now entirely abandoned. It is now commonly held that God simply gave His Church the power to set aside whatever day or days she would deem suitable as Holy Days. The (Roman Catholic) Church chose Sunday, the first day of the week, and in the course of time added other days as holy days.” John Laux, A Course in Religion for Catholic High Schools and Academies, 1936 edition, vol. 1, p. 51.
“Protestantism, in discarding the authority of the (Roman Catholic) Church, has no good reasons for its Sunday theory, and ought logically to keep Saturday as the Sabbath.” John Gilmary Shea, American Catholic Quarterly Review, January 1883.
“The Catholic church for over one thousand years before the existence of a Protestant, by virtue of her divine mission, changed the day from Saturday to Sunday...The Protestant World at its birth found the Christian Sabbath too strongly entrenched to run counter to its existence; it was therefore placed under the necessity of acquiescing in the arrangement, thus implying the (Catholic) Church’s right to change the day, for over three hundred years. The Christian Sabbath is therefore to this day, the acknowledged offspring of the Catholic Church as spouse of the Holy Ghost, without a word of remonstrance from the Protestant World.” James Cardinal Gibbons in the Catholic Mirror, September 23, 1983
“They [the Protestants] deem it their duty to keep the Sunday holy. Why? Because the Catholic Church tells them to do so. They have no other reason...The observance of Sunday thus comes to be an ecclesiastical law entirely distinct from the divine law of Sabbath observance...The author of the Sunday law...is the Catholic Church.” Ecclesiastical Review, February 1914.
“The Sunday...is purely a creation of the Catholic Church.”American Catholic Quarterly Review, January 1883.
“Sunday...is the law of the Catholic Church alone...” American Sentinel (Catholic), June 1893.
“Sunday is a Catholic institution and its claim to observance can be defended only on Catholic principles...From beginning to end of Scripture there is not a single passage that warrants the transfer of weekly public worship from the last day of the week to the first.” Catholic Press, Sydney, Australia, August 1900.
“It is well to remind the Presbyterians, Baptists, Methodists, and all other Christians, that the Bible does not support them anywhere in their observance of Sunday. Sunday is an institution of the Roman Catholic Church, and those who observe the day observe a commandment of the Catholic Church.” Priest Brady, in an address reported in The News, Elizabeth, New Jersey, March 18, 1903.
It is all according to whom you recognize as the authority in this matter, God or the institutions of men.
