There's a difference between knowing God will provide and presumption about it. Otherwise, heck, I'll get married and start a family while flipping burgers at McDonald's ... because, after all, God will provide. All things being equal, men should build up some financial security and independence before embarking on marriage and not presume upon God to just "provide".
That's your opinion though. If a man is willing to work "jobs" (anything available, manual labor, retail) instead of a career, and only has a full time McDonald's job, there's nothing wrong with this man, being a Traditional Catholic, getting married for life and taking on the obligation of providing for his wife and whatever children result from the marriage.
God WILL provide. That means God will provide.
No, you're not tempting God by getting married when you meet the right person. Or getting married without a huge nest egg, an impressive career, etc.Sometimes having a wife and children dependent on him is exactly what a man needs to focus himself, grow up, and overcome the obstacle (e.g., "where is baby #3 going to sleep?") I've seen hundreds of cases of this, in real life, online, books, etc.
We have no guarantees in life. Baby Boomers started this thing called "insurance" trying to guard against everything God might allow to happen to us, every misfortune, every suffering. But that is an illusion. You can't escape suffering, and you can plan for everything. The future is unknown, and there are no guarantees in life. You have to keep that in mind.
That is why the Catholic Church doesn't have any "teaching" on how many assets you need for marriage, what kind of house you must own, or what your minimum salary must be.The bank requires you provide proof of full coverage insurance (the car itself, as well as liability insurance) before they'll loan you money for a car. But the Church doesn't require any proof of insurance(s) before you get married. Hmmmm...
If it was even a matter of wisdom, she would provide such advice. But it's not. It really just depends on the person.
Look at the Gaza strip. 1/2 the population is under 18. They reproduce like rabbits. And they are living in an open-air prison with 35% unemployment. You think each of those children was born to a man with a stable career, a paid off house, etc.? Yeah right. But the Gazans, in their poverty, are more typical of what you'd find in history -- including Catholic Europe.
Young men and women are attracted to each other, as designed by God. It all leads to children, also designed by God. We shouldn't thwart this plan for some baby boomer ideal of "security", homeownership, Middle Class lifestyle, suburbia, the American Dream, insuring against every possible misfortune, vaccinating against every possible disease, and trying to escape every possible future suffering.
