The Sacrament of Matrimony

When Jesus came he raised the power of matrimony almost to where it was when Adam and Eve were on Earth. The difference now is that the marriage is built off of grace going through our sins rather that grace without sins which is how it was in the beginning. He made it a sacrament which is the way through which humans on Earth are able to have their sins after baptism forgiven. This means that a marriage between two baptized Catholics is a sacramental marriage and will never go away. This means that if a baptized Christian divorces another baptized Christian and they divorce if one of the two is remarried then they, according to Jesus, will be living in a state of perpetual adultery and mortal sin.

This is shown when Luke writes, "Everyone who divorces his wife and marries another   commits adultery, and he who marries a woman divorced from her husband commits adultery" (Luke 16:18; cf. Mark 10:11–12). Paul is also insistent about this point too. He says, "Thus a married woman is bound by law to her husband as long as he lives. . . . Accordingly, she will be called an adulteress if she lives with another man while her husband is alive" (Rom. 7:2–3). 

This only applies to a marriage between two people for there is a different rule for an unbaptized person’s marriage. In Greco-Roman culture it is easy to divorce and remarry which led the Church Fathers to proclaim Jesus’ teaching about the matter to them. Other Church denominations have modified this rule to accommodate the new and modern culture’s thought on divorce and remarriage. These changes lead the Catholic Church to be one of the few denominations that still preserves Jesus’ and the early Christian’ view on divorce.

    This means that a marriage between two people who have been baptized can not remarry unless the spouse has died or there was a never an actual valid sacramental marriage. It’s like this, a marriage has to be contracted for it to be official, for it to be contracted the bride and groom have to share matrimonial consent. If there is no consent the marriage is null and the two are allowed to remarry.

    This because without the consent there is no need for a divorce.

This is a commandment that comes from Jesus through Paul when he writes, "To the married I give charge, not I but the Lord, that the wife should not separate from her husband (but if she does, let her remain single or else be reconciled to her husband)—and that the husband should not divorce his wife" (1 Cor. 7:10-11). This is why Jesus established matrimony as a sacrament so that God’s grace will pour into us in times of trial when our marriages are in trouble.
