For the devil, there are many ways to skin the cat, so let's start putting together his methods for taking the young away from our chapels
(the true faith LIVED), as I observed the last 20 +years in tradition. These are some ways mentioned so far, and my quick observations:
Hard to have a "foundation " when everything and everyone calling themselves Catholic all contradict each other. Vatican II contradicts all of its predecessors. Francis the same. Novus Ordo and Tradition both claim to be heirs to the throne of Peter. +Fellay contradicts +Lefebvre, Sedes contradict Recognize and Resist, now we have "Resistance". Even apparitions prophecies, including Fatima, seem to drag on for centuries.
People I know who were raised in good Catholic families who were well catechised throw up their hands....and say enough is enough. I'm just going to follow my heart.
It is the parents fault. They didn't bother to seek truth and their children ill prepared, continue in the same path.
Statistically, trad young adults are just as infected with 'the world' as any other young adult population. As atheism is growing, so a small % of trads will be infected with this and their Faith will become lax and they may stop going to church for a while. I've seen this more than a few times.
As the indult grows, a large % will leave tradition and attend this. At our chapel, we've lost about 70% of one generation to the indult. Young adults, who haven't read anything about V2 or the new mass, who only care about social media, get duped by the 'positive and happy' novus ordo-ites who think that "the latin mass is coming back! Everything's going to be rosy". Plus, the millenial generation cannot stand to be an "outsider" or "different", as they want to be "part of the group" just like on facebook. They compromise their faith because of human respect. ...Or they started dating novus ordo/indult catholics and didn't want to 'rock the boat' by trying to convert them to tradition. So they compromised and went to the indult, for love.
Then, there's the normal % of trads who have just given into a partying/fun life. They may still go to mass, but their faith is very weak. A good percentage of these will 'grow up' and become decent catholics at some point. But, some will not.
Finally, there are some who have kept the Faith, lived 'boring' lives, are looked at as 'old fashioned' and who have grown in virtue. These are small in number but they are a great example.
Really, aren't the above 4 categories consistant with the parable of the "Sower of the Seed"?
One more, giant reason they leave a chapel is for work in another town.
Here are some more reasons from my experience watching parents do it wrong, and I blame the parents for the children's loss of the faith (if they ever really received it)
- the parents themselves are lax examples in some area or in many; in clothing (immodesty), in the way they think girls can attract men, in bending the rules, in not paying attention to their children by just watching out for themselves (the parents could be very religious, but they pay no attention to their children). The family is like a fort to protect the family from the enemy, the world, the devil. Some trad families have forts with only three walls completed, the world can easily come and go inside as it pleases. Some families have four walls, however, they are too low, again the world can get in easily. Some parents have high thick strong walls, howver, they leave the gates open.
It takes a fort with high thick walls and the gates constantly manned and the leaders (the parents and the older children who were raised in the good fort) always on the alert and up to date of new techniques of the devil.
In my experience, scant few parents care or are prepared for the battle. Most trads are naive to the world (and lazy), just want their priest and SSPX schools to take care of their children.
Like I said above, a big reason the young people leave the chapels is to find work. The reason for this is that in the USA (that is where I live, though I was not born here) American parents are like snakes. They lay their eggs, and the children are left to fend for themselves to learn an occupation. Naturally, the children will leave the house and go find work out of town and then start a family and lay their own eggs, and the cycle will continue.
In Italy, Spain, and South America as examples (Catholic cultures) the father teaches his sons the business, and the sons stay with the family. The mothers teach the girls to cook and take care of the family, and do work the women can do, like the accounting for the family business. American parents let their children play, while they cook and work, never passing on any knowledge to their children, strictly letting the schools do it.
