Your own church says that all TEN of the TEN Commandments are applicable to Gentiles. (Including the Sabbath Commandment)
Did we not cover that point already?
CCC - Catholic Church Catechism
The obligation of the Decalogue
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.
1 Cor 7:19 "what matters is KEEPING the Commandments of God:"
and how do we "show" love for God?
1 John 5:2-3 answers that question
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.
2063....
the words of the Decalogue remain likewise for us Christians. Far from being abolished, they have received
amplification and development from the fact of the coming of the Lord in the flesh.

The Council of Trent teaches that
the Ten Commandments are obligatory for Christians and that
the justified man is still bound to keep them;
28 The Second Vatican Council confirms: "The bishops, successors of the apostles, receive from the Lord . . . the mission of teaching all peoples, and of preaching the Gospel to every creature, so that all men may attain salvation through faith, Baptism and the
observance of the Commandments."

(Application in James 2)

The Decalogue forms a coherent whole. Each "word" refers to each of the others and to all of them; they reciprocally condition one another. the two tables shed light on one another; they form an organic unity.
To transgress one commandment is to infringe all the others.
30 One cannot honor another person without blessing God his Creator. One cannot adore God without loving all men, his creatures. the
Decalogue brings man's religious and social life into unity.
