Moral questions and legan fiat

[Pedrito]

From Post #14 on Page 2:

Marriages are something that people do. God gave commandments to Israel about how to handle a marriage and how to terminate one. Jesus gave Christians a different perspective on marriages indicating that they cannot be terminated except by the death of one (or both) of the married people. Sacramental marriage is a reflection of the union between Christ and the Church. Civil marriages are increasingly like civil contracts that are made and broken like other civil contracts. Civil marriages are not sacramental marriages. A couple married under civil law who have not also sanctified their marriage as a sacrament probably ought to do so. I cannot say more at this time because I have not studied the matter.

(One wonders if that Poster feels informed enough, based on his statement “A couple married under civil law who have not also sanctified their marriage as a sacrament probably ought to do so”, to answer the following simple questions.)

Are marriages entered into by millions of people around the world, in different cultures, and not Roman Catholic by religion, valid in the God of the Roman Catholic Church’s eyes or not?

Does that God consider they are all living in sin (guilty of fornication) unless and until their marriages are made “sacramental” by the Holy Roman Catholic Church?

If not, then what is the practical advantage of taking that step? And what are the practical disadvantages of not doing so?

Also, that Poster has yet to comment on the Scriptural perspectives offered in Post #13:

It will be interesting to see what the stance of the Catholic Church will be (or maybe already is) in the light of:
1 Corinthians 6:9,10: “9 Do you not know that the unrighteous shall not inherit [the] kingdom of God? Do not be deceived; neither fornicators, nor idolaters, nor adulterers, nor abusers, nor homosexuals,
10 nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit [the] kingdom of God.” (MKJV)
and
Galatians 5:19-21: “19 Now the works of the flesh are clearly revealed, which are: adultery, fornication, uncleanness, lustfulness,
20 idolatry, sorcery, hatreds, fightings, jealousies, angers, rivalries, divisions, heresies,
21 envyings, murders, drunkennesses, revelings, and things like these; of which I tell you before, as I also said before, that they who do such things shall not inherit the kingdom of God.” (MKJV)

Shouldn't the Catholic Church deny access to all church sacraments, to people defined in those statements?

Could it be that it all depends on whether at this particular point in its history, the Catholic Church chooses to regard those apostolic statements as directly inspired declarations from God, or simply "pastoral advice" originating from a human?
