“The Sun was a foremost god with heathen-dom…The sun has worshippers at this hour in Persia and other lands…. There is, in truth, something royal, kingly about the sun, making it a fit emblem of Jesus, the Sun of Justice. Hence the church in these countries would seem to have said, to ‘Keep that old pagan name [Sunday]. It shall remain consecrated, sanctified.’ And thus the pagan Sunday, dedicated to Balder, became the Christian Sunday, sacred to Jesus.” William Gildea, Doctor of Divinity, The Catholic World, March, 1894, p. 809
“The retention of the old pagan name of Dies Solis, for Sunday is, in a great measure, owing to the union of pagan and Christian sentiment with which the first day of the week was recommended by Constantine to his subjects – pagan and Christian alike – as the ‘venerable’ day of the sun.”” Arthur P. Stanley, History of the Eastern Church, p. 184
Sun worship is paganism and started long ago by Nimrod. This is what the Catholic Church confesses about Sunday worship being paganism:
“…pastoral intuition suggested to the Church the christianization of the notion of Sunday as “the day of the sun”, which was the Roman name for the day and which is retained in some modern languages.(29) This was in order to draw the faithful away from the seduction of cults which worshipped the sun, and to direct the celebration of the day to Christ, humanity’s true “sun”.” John Paul II, Dies Domini, 27. The day of Christ-Light, 1998 (Prominent protestant leaders agree with this statement – See here for a statement by Dr. E. T. Hiscox, author of the ‘Baptist Manual’)
“Protestants do not realize that by observing Sunday, they accept the authority of the spokesperson of the Church, the Pope” (Our Sunday Visitor, February 5, 1950).
“Sunday is our MARK of authority… the church is ABOVE the Bible, and this transference of Sabbath observance is proof of that fact” (Catholic Record of London, Ontario Sept 1, 1923).
“Protestants … accept Sunday rather than Saturday as the day for public worship after the Catholic Church made the change… But the Protestant mind does not seem to realize that … in observing Sunday, they are accepting the authority of the spokesman for the Church, the pope.” Our Sunday Visitor, February 5th, 1950.
“… 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.” The Faith of Our Fathers, by James Cardinal Gibbons, Archbishop of Baltimore, 88th edition, page 89. Originally published in 1876, republished and Copyright 1980 by TAN Books and Publishers, Inc., pages 72-73.
“The Sabbath was Saturday, not Sunday. The Church altered the observance of the Sabbath to the observance of Sunday. Protestants must be rather puzzled by the keeping of Sunday when God distinctly said, ‘Keep holy the Sabbath Day.’ The word Sunday does not come anywhere in the Bible, so, without knowing it they are obeying the authority of the Catholic Church.” Canon Cafferata, The Catechism Explained, p. 89.
