- This is the day which the LORD has made; let us rejoice and be glad in it.103
The day of the Resurrection: the new creation
2174 Jesus rose from the dead "on the first day of the week."
104 Because it is the "first day," the day of Christ's Resurrection recalls the first creation. Because it is the "eighth day" following the sabbath,
105 it symbolizes the new creation ushered in by Christ's Resurrection. For Christians it has become the first of all days, the first of all feasts, the Lord's Day (
he kuriake hemera, dies dominica) Sunday:
- We all gather on the day of the sun, for it is the first day [after the Jewish sabbath, but also the first day] when God, separating matter from darkness, made the world; and on this same day Jesus Christ our Savior rose from the dead.106
Sunday - fulfillment of the sabbath
2175 Sunday is expressly distinguished from the sabbath which it follows chronologically every week; for Christians its ceremonial observance replaces that of the sabbath. In Christ's Passover, Sunday fulfills the spiritual truth of the Jewish sabbath and announces man's eternal rest in God. For worship under the Law prepared for the mystery of Christ, and what was done there prefigured some aspects of Christ:
107
- Those who lived according to the old order of things have come to a new hope, no longer keeping the sabbath, but the Lord's Day, in which our life is blessed by him and by his death.108
2176 The celebration of Sunday observes the moral commandment inscribed by nature in the human heart to render to God an outward, visible, public, and regular worship "as a sign of his universal beneficence to all."
109 Sunday worship fulfills the moral command of the Old Covenant, taking up its rhythm and spirit in the weekly celebration of the Creator and Redeemer of his people.
Quotations from the Convert's Catechism of Catholic Doctrine.
"Have you not any other way of proving that the Church has power to institute festivals of precept?"
"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" Stephen Keenan, A Doctrinal Catechism 3rd ed. p. 174
How prove you that the Church hath power to command feasts and holydays?
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." Henry Tuberville, An Abridgment of the Christian Doctrine (1833 approbation), p.58 (Same statement in Manual of Christian Doctrine, ed. by Daniel Ferris [1916 ed.], p.67)
"The Catholic Church,... by virtue of her divine mission, changed the day from Saturday to Sunday.
" The Catholic Mirror, official organ of Cardinal Gibbons, Sept. 23, 1893.
"Is Saturday the 7th day according to the Bible and the 10 Commandments?"
"I answer yes".
"Is Sunday the first day of the week and did the Church change the 7th day, Saturday, for Sunday, the 1st day?"
"I answer yes".
"Did Christ change the day?"
"I answer no!" Faithfully yours, "J. Cardinal Gibbons" Gibbons' autograph letter.
Which is the Sabbath day?
Saturday is the Sabbath day.
Why do we observe Sunday instead of Saturday?
We observe Sunday instead of Saturday because the Catholic Church transferred the solemity from Saturday to Sunday."
Peter Geiermann, The Convert's Catechism of Catholic Doctrine (1946 ed.), p.50. Geiermann received the "apostolic blessing" of Pope Pius X on his labors, January 25, 1910.
"The Catholic Church changed the observance of the Sabbath to Sunday by right of the divine, infallible authority given to her by her Founder, Jesus Christ. The Protestant, claiming the Bible to be the only guide of faith, has no warrant for observing Sunday.
