Well, in France Catholic schools have to teach the same things as public school as they are mostly public-funded, and the children are not a lot different than in public school. there is just more children from practicing Catholic families. It is just a normal school just an optional Catholic class.
So of course they have biology lessons where they are teach the same thing such as the different forms of contraception and the basic of intercourse, of procreation, abortion, in vitro fertilization… But not natural methods of family planning. And all this is of course not linked at all with marriage.
But that’s nothing to do this theology classs such as written in this article.
For eg, me (20 years ago) i learnt basic of intercourse and procreation in biology class at 12.
We have a group talk at 13 on sexuality, but we speak more on affective relationship. there is no graphic image etc. parents have to sign a paper. That’s less than in this article.
In the catholic school I worked, the biology teacher have ask to 15/16 years old children after the lesson on contraception to each girl individually and in front of all the students “if you fall pregnant
now, would you abort or not?”
