Think YOU missed the point
I never said the ONLY subject should be foreign language, nor that it must be French. I said a foreign language used to be considered PART of a proper education. As for Japanese or Chinese being more useful: as it happens I did, for a wonderful job, learn and work in Cantonese and have used Japanese and, no, in IT or even banking, unless you are a Far East specialist, Mandarin etc. are not more useful than a widely spoken (as opposed to large number of speakers) language such as French, Spanish or German (German is very useful in places like Turkey and much of Eastern Europe, as well as being, probably, the language with the most speakers in the EU, French will get you by in a lot of Africa and various Arab countries and parts of SE Asia and the Pacific, while Spanish and Portuguese will serve you will in S. America (USA too in some areas), parts of N. Africa and so on for other European languages.
Of course, one can learn a language in many ways and I have had to use formal and informal methods myself, the results of the latter showing in my written and painfully (for the listener) spoken variants. However, academic study of any discipline, but especially language (which usually covers more than just the spoken variant, including literature, culture and the discipline of grammar) is a very good intellectual and social training - some of the best IT people I have known have been linguists, two being classicists, other good ones seeming to come from microbiology, biology or chemistry.
So, my point would be: any rigorously studied subject is a good training for most jobs; languages for at least part of one's education have the added benefit of being useful both professionally and privately. Religion is, to my mind a private affair and I would mention it on a CV only if I was really a devout whatever-ist and I wanted to be sure my religious life and the job are compatible or if it is relevant to the job. Otherwise, keep your self-selling to the usual run of sport, hobbies etc. (and be careful, my stepfather, a keen golfer, refused to employ anyone who put Golf on their CV, on the presumption that they would take too much time off to play it. Others I know refuse skiers, footballers and mountaineers because of the likelihood of injury and time off to recover).
