Can you quote where the Church has taught this is marriage's primary purpose?
St. Thomas ranks Baptism as the most important sacrament. He ranks Matrimony last "because it has less participation in the nature of the spiritual life, to which the sacraments are ordained".
Thus, married Catholics are more sanctified by the top 5 sacraments (esp. Baptism and Eucharist) than by marriage.
(To enter marriage with the primary and sole purpose of sanctifying oneself and not to have children would render the marriage invalid.)
The post-Vatican II teachings that make mutual love of the spouses the primary end of marriage tend to glorify the sanctifying aspect of marriage to such an extent that they degrade the necessity of the other sacraments (which Paul VI bastardized anyways with his Modernist Novus Ordo new-sacraments). Sanctify-yourself-with-more-sex-and-fewer-sacraments is certainly more appealing to "modern man" than the Eucharist or Penance, so it makes sense why the cult of man Novus Ordo sect promotes abominations like "Theology of the Body".
Yes, that's marriage's primary end.
Sure, as in contraception, sodomitical acts, etc., but one can use the evil of concupiscence for a good purpose in marriage:
Contra Iulianum 5.60:(For more quotes along these lines, see §2. "Saint Augustine and 'Putting Bad to Good Use'" of this article)
Geremia, you constantly put words into people's mouths.
t would help if you would learn to read. Take it slowly. Don't rush.
No person here, no poster here has ever suggested that they have entered marriage with the idea of not having any children. I know a lot of couples who are in the process of sanctifying themselves by prayer and by regularly partaking of the Holy Sacraments, and of sanctifying their children too. Our home is meant to be a domestic church.
We must raise our children in the faith by:
(N/B: not in order of importance)
1. worshiping, praising, and glorifying our Lord God and Saviour, Jesus Christ
2. honoring the Blessed Virgin Mary and all the saints.
3. praying daily with our children
4. practicing the Faith with our children
5. being good examples to our children and to each other
6. taking our children to church to receive the Holy Sacraments
7. practicing the Faith with our children
8. obeying the Ten Commandments and the Commandments of the Church
9. homeschooling our children
10. watching our children diligently and not leaving them alone with strangers who may harm them.
