Part 19 BEGINNING OF A SET OF POSTS on the ENDS OF MARRIAGE
I have treated the efficient cause of marriage and the formal cause of marriage. It is now time to treat the final cause of marriage. The purpose for which it was instituted.
This is a complex matter in some senses. Let us say that there are different vantage points to take on the matter, objective and subjective. By “objective” I mean that viewpoint that takes into consideration the order of ends intended by the one who instituted marriage, God. By “subjective” I mean the viewpoint by which an individual human approaches the institution.
Sometimes, the objective order does not exactly coincide with the subjective order. We see this especially with children. If you want them to practice piano, you offer treats for cooperation and you take away privileges for lack of cooperation. The child seeks the reward primarily, not the good of being musical. However, you intend the good of being musical, and this is the superior good.
We see something similar (although by no means identical) when it comes to the ends of marriage.
The Church has taught through many centuries that the Primary End of Marriage is the Procreation and Education of Offspring.
