Because the Ten Commandments and the New Covenant are "just for Israel" in your mind?
"Sabbath as Saturday" -- does the Bible say it any other way?
===============================
Does the RCC teach that the Sabbath Commandment is only for Jews?
Dies Domini by Pope John Paul II calls for "civil penalties" for failure to observe the Papal Sabbath.
Dies Domini -
47. Even if in the earliest times it was not judged necessary to be prescriptive,
the Church has not ceased to confirm this obligation of conscience, which rises from the inner need felt so strongly by the Christians of the first centuries. It was only later, faced with the half-heartedness or negligence of some, that
the Church had to make explicit the duty to attend Sunday Mass: more often than not, this was done in the form of exhortation, but at times the Church had to
resort to specific canonical precepts. This was the case in a number of local Councils from the fourth century onwards (as at the Council of Elvira of 300, which
speaks not of an obligation but of penalties after three absences)(78) and most especially from the sixth century onwards (as at the Council of Agde in 506).(79) These decrees of local Councils led to a universal practice,
the obligatory character of which was taken as something quite normal.(80)
Dies Domini pt 13 -
"the Sabbath ...is therefore rooted in the depths of God's plan. This is why
unlike many other laws - it is not within the context of strictly cultic (Jewish) stipulations but within
the Decalogue the "ten words" which represent the very
pillars of moral life inscribed on the human heart!! In setting this commandment within the context of the basic structure of ethics, Israel and then the church declare that they consider it not just a matter of community religious discipline but a defining and indelible expression of our relationship to God, announced and expounded by biblical revelations.

The word "Decalogue" means literally "ten words."11 God revealed these "ten words" to his people on the holy mountain. They were written "with the finger of God,"
12 unlike the other commandments written by Moses.13 They are pre-eminently
the words of God. They are handed
on to us in the books of Exodus
14 and Deuteronomy.
15 Beginning with the Old Testament, the sacred books refer to the "ten words,"
16 but it is
in the New Covenant in Jesus Christ that
their full meaning will be revealed.
2072 Since they express man's fundamental duties towards God and towards his neighbor, the
Ten Commandments reveal, in their primordial content,
grave obligations.They are fundamentally immutable, and
they oblige always and everywhere. No one can dispense from them. the Ten Commandments are engraved by God in the human heart.
====================
The Catholic Commentary on the Baltimore Catechism post Vatican II - argues the SAME two points.

The Faith Explained" page 243
"we know that in the O.T it was the
seventh day of the week - the Sabbath day- which was observed as the Lord's day. that was the law as God gave it...'remember to keep holy the Sabbath day.. the early Christian church determined as the Lord's day the first day of the week.
That the church had the right to make such a law is evident...
The reason for
changing the Lord's day from Saturday to Sunday lies in the fact that to the Christian church the first day of the week had been made double holy...
nothing is said in the bible about the change of the Lord's day from Saturday to Sunday..that is why we find so illogical the attitude of many non-Catholic who say they will believe nothing unless they can find it in the bible and yet will continue to keep Sunday as the Lord's day on the say-so of the Catholic church
