I have little doubt that you are right about the motivation for sending children to Catholic schools. The difficulty I see is with what you describe as the desire for the child to “grow in our faith”. In my view, a child cannot have true faith until they are old enough to understand it properly. Children will have faith in many things, but it is blind faith until they are able to properly employ reason.
I don’t see blind faith as a commendable thing. Hence my opinion that it would be better to teach children about religious beliefs when they are old enough to understand it. A parent’s wish for their child to grow up with appropriate moral values seems eminently sensible. But not so to wish that their child grows up blindly believing the same things that they do.
There is more to being a christian than employing reason. There is a call to holiness and children being innocent and pure are closer to holiness than you or I. We adult christians can learn from christian children.
Child Saints feature in the Catholic, Orthodox, Anglican and Lutheran churches.
"St. Dominic Savio died at the age of 14 in 1857. When he was canonized a saint in 1954 by Pope Pius XII, he was (and remains) the youngest person ever to have been canonized a saint by the Catholic Church without being some sort of martyr.
Born and raised in Italy, Dominic showed signs of sanctity early on. When he was just 4 years old Dominic was frequently found by his parents in solitary prayer. He learned to be an altar boy at age 5, and if he got to the church before the priest unlocked the doors in the morning, he would kneel (in the mud, snow, whatever) until the priest arrived. When he was just 7 years old, he wrote in his journal that he had four rules:
- I will go to Confession often, and as frequently to Holy Communion as my confessor allows.
- I wish to sanctify the Sundays and festivals in a special manner.
- My friends shall be Jesus and Mary.
- Death rather than sin.
He happened to attend the school of St. John Bosco, and John became a mentor for Dominic.
As a pre-teen, he experimented with severe physical penances (putting rocks in his bed, wearing a hair shirt, etc), but when his superiors found out, they forbade him from continuing them. Instead, he decided to simply perform all of his duties with as much love and humility as possible, which he summed up with the motto, “I can’t do big things but I want everything to be for the glory of God.” (Remind you of another saint?)
Unfortunately, he contracted a lung disease and died soon after. After he died, John Bosco wrote a biography of Dominic, which was instrumental in Dominic being canonized."
