From my 60+ years experience, 39 years as a wild man, 25+ years as a traditionalist, and of those 25 years, 17 years as a father, I know the world side very well. I was a king in that world, an alfa male wolf, now I am a shepherd. Domesticated wolves make good shepherds of daughters, because they know all the male tricks and in my case I know the female weaknesses. I have almost all girls, 5+, and few boys. Below is a list of the errors that I see parents making today , but first, I will speak of a family which is
the example of what a Catholic family can accomplish and the goal:
I have known a family of 10+ children, the mother is the one that really raised the children in the faith. She homeschooled them to the 7th to 9th grade, and by the providence of God, people gave her the money to pay for the education of all the children from 7th, 8th, 9th till graduation from high school. They all went to SSPX schools. She was very strict with the children and taught them the faith. She slaved over the children all her life and the children knew it. She was not the loving type in the sense of communicating her love verbally, but she showed it in her actions. All her children are now married to what I consider excellent wives and husbands, I could not ask for better for my children, in fact, I think it would be difficult to find the same quality. In the case of this woman, she did her job and God provided her with whatever she needed. One gift from God was that all the boys ( and the girls) were put to work by someone else (In many cases, the same person who later paid their education) from the time they were old enough to hold the other end of a 2x4, or fold clothes. As they grew in their working knowledge they became professionals in many fields. The mother always relied on God's Providence to provide what she could not, and she worked like a slave. God gave her everything. She was an example to my wife and I. She was strict, but there is much more to it, than being strict.
My list of the errors that I see parents making today
#1 - they do not know the why of the faith, and thus they teach the children the faith by force, or send them to a teacher. I call this the "ask Fr." syndrome, anything you want to know just ask Father. Their knowledge of religion is superficial, and never gets past it, because they can just ask Father. The children's faith will be just as superficial, never having learned the "why's", and as soon as it is challenged, they go with the world.
#2 - the parents do the same with everything else one needs to know about life. They do not teach the why's of working, life (our purpose in life), politics/government, manners, civility, culture...
#3 - the parents do not talk to their children nor listen to what they are talking about, nor observe how their children behave with their peers and adults. Thus they know nothing about their own children.
#4 - Some trad parents are so preoccupied with teaching the faith to strangers (even writing books, and lecturing) about subjects like Novus Ordo heresy, sedevacantes, Jєωs, Masons..... , while they pay no attention to what they can control, their children.
#5 - mothers (and fathers) because they were lucky to find a good mate by "cheating" (going out with persons of the opposite sex by themselves. Having pre-marital kissing, fondling, intercourse), think that their children will have the same luck. So, they allow their children to use the same methods. This is a big one, very common for all the wrongs the children fall into.
I'll leave it that that for now.
