My point is that Genesis 2 refers to the Seventh Day Sabbath, not Sunday. And yet that is where the Pope tries to infer that Sunday should be kept as such, namely, a work free day, in fact that is what the Catholic Bishops are trying to get through in EU, having Sunday be a work free day.
From the article:
“Work and celebration are intimately connected in the life of families: they condition choices, influence relations between married couples and between parents and children, affect the relation of families with society and with the Church. Holy Scripture (cf. Genesis 1-2) tells us that the family, work and the feast day are gifts and blessings of God to help us to live a fully human existence. Daily experience attests that the authentic development of the person includes the individual, familial, and communal dimension, activities and functional relationships, as well as openness to hope and to the Good without limits.
In our days, unfortunately, the organization of labor, conceived and realized in function of market competition and maximizing profit, and the concept of feast as an occasion for escape and consumption, contribute to the break-up of the family and the community and to the spreading of an individualistic lifestyle. Thus, it is necessary to promote reflection and efforts at reconciling the demands and the periods of work with those of the family and** to recover the true meaning of the feast, especially on Sunday, the weekly Easter, the day of the Lord **and the day of man, the day of the family, of the community and of solidarity.”

The Third Commandment Expounded
Q. 431. WHAT is the third commandment?
A. Remember that thou keepest holy the sabbath day.
Q. 432. When did the Sabbath begin to be kept?
A. From the very creation of the world; for then God blessed the seventh day, and rested
on it from all His works. Gen. ii. 2.
Q. 433. When was this commandment renewed?
A. In the Old Law; when God gave the commandments to Moses on mount Sinai, written
with His own finger in two tables of stone, Exod. xx. 1, &c. xxxi. 18.
Q. 434. Why was the Jewish Sabbath changed into the Sunday?
A. Because Christ was born upon a Sunday, arose from the dead upon a Sunday, and sent
down the Holy Ghost on a Sunday: works not inferior to the creation of the world.
Q. 435. By whom was it changed?
A. By the Governors of the Church, the Apostles, who also kept it; for St. John was in
spirit on the Lord’s day (which was Sunday.) Apoc. i. 10.
Q. 436. How prove you that the Church hath power to command feasts and
holydays?
A. 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.
Q. 437. How prove you that?
A. 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.
Q. 438. What other proof have you?
A. Out of John x. 22, where we read that Christ himself was present, and kept the
Dedication of the temple in Jerusalem, a feast ordained by Judas Maccabæus, 1 Macc. iv.
59.
And out of Acts ii. 1, 4, where the Apostles, keeping the feast of Pentecost, “were all
filled with the Holy Ghost.” Neither do Protestants as yet differ from this, though some
have lately prohibited and profaned both it and the holy feast of the Resurrection, and all
the other feasts of the Church.
Q. 439. What commandment have you from God for obedience to the Church in
things of this nature?
A. Out of Acts xv. 41, where we read that “St. Paul went about confirming the Churches,
and commanding them to keep the precepts of the Apostles and the ancients.” And out of
Luke x. 16, “He that heareth you, heareth me; and he that despiseth you (the Church)
despiseth me.”
Q. 440. May temporal princes and the laity make a holy day?
A. With consent and approbation of the Church, they may, otherwise not; because this is
an act of spiritual jurisdiction.
Q. 441. For what end doth the Church ordain holydays?
A. For the increase of piety, and the memory of special benefits received from God.
Q. 442. If keeping the Sunday be a church precept, why is it numbered in the
decalogue, which are the Commandments of God, and the Law of Nature?
A. Because the substance or chief part of it, namely Divine Right, and the Law of Nature;
though the determinating this particular day, Sunday rather than Saturday, be a Church
ordinance and precept.
Q. 443. Did not Christ, when he confirmed the rest, confirm also this
commandment?
A. In as much as it belongeth to the law of nature, he did: but not as it belonged to the
ceremonial law of the Jews, and was affixed to Saturday, therefore, now we are not
bound to keep Saturday.
Q. 444. Why so, I pray you?
A. Because that particular day was a command of the ceremonial law of the Jews, which
was abrogated, and ceased to oblige after the death of Christ.
Q. 445. To what are we obliged by this precept?
A. To spend Sunday in prayer and divine service.
Q. 446. What is the best means to sanctify the Sunday?
A. By hearing mass, confessing our sins, communicating, hearing sermons, and reading
good books.
Q. 447. What is forbidden by this precept?
A. All profane employments, and servile labours, excepting such as are of necessity, as
dressing meat, serving cattle, &c. or such as appertain to piety and works of mercy.
Q. 448. Who break this commandment?
A. Such as without necessity spend any considerable part of the Sunday in servile
labours.
Q. 449. How else is the Sunday profaned?
A. By spending all the morning slothfully in bed, or vainly dressing ourselves; by missing
divine service when we may hear it, or spending a part of the day in drinking, gaming,
dancing, or the like.
How about we enact a new law forcing all businesses to close on Sunday except for emergency services? 
) then it certainly is logical to accept that we should too.
