Can. 1141 A marriage that is ratum et consummatum can be dissolved by no human power and by no cause, except death.
Canon Law states that only by death does the Sacrament dissolve. But, would the Law neglect that the person who was then elevated to and in that Union, being One Flesh with their spouse, had an experience which he or she can never forget? Let alone, the growth which they attained in that Union? Would then that the Sacramental state of that Union have also dissolved, being in One Flesh by the Consummation and Fulfillment in that Union having children? Would the father (supposing his wife passed away(, say, the children are no longer tied in the Sacrament of that Union which they were fulfilled in being?
The power of death actually has no power over that Union either. For it was that Christ though died, conquered death. And since by way of Him, it is the Sacrament of Marriage, though be it through death He laid down His life for His Bride. The Church, thus through His Death and Resurrection, became Consummated in that Union. It was the Celebration of His Wedding Feast, that becomes the Celebration around Pentecost. The Confirmation of the Holy Spirit, was in this way and to that end. The Consummated Union of the Church in Whole. Wherefore as the life breathed into Adam. Thus, the Holy Spirit breathed life into the Church as the Consummated end, as the same Holy Spirit which overshadowed Mary, and Christ was born. This is the fulfillment of that Union. The Apostle’s become like Christ. Saint Peter does not deny, but upholds (Act of the Apostle’s.) He does not detract, but lives as Christ in being nailed to a Cross, even upside down. The Martyrs then exist.
By the way, to note, Canon Law can change. And that does not mean Canon Law is without error.

That is not to question the authority of the Church either. However, the Church has a problem with marriage, because people tend to abuse the Sacrament. People who are co-habitating. Having sex before marriage and not going to Confession. And, yes, people who want to endorse homosexual unions, and what not. In other words, people can change Canon Law. And that is where it is prone to error. Will it change? I hope not. However, it can.
Thus, Canon Law by and in of itself cannot dictate nor define a Sacrament. Canon Law must beholden to what Christ said, did, and taught. And that also means bearing upon Judaic roots and origins as well. From the Patriarchs of Our Faith, and the Fathers of the Church.
If the Church had the moral heresy of moral relativism. And should priests and Bishops, and Cardinals (and Pope) fall into being moral relativists. And chose to change Canon Law to fit the times. Then, it is prone. You therefore cannot posit that Canon Law and in/of itself has the final authority and word if it fails to hold up to the Sacraments>
