re: family size

It may not all have something to do with the Mass, but I think it does have something with to do with the concept I have increasingly encountered whereby any document on Catholic faith or morals which existed prior to Vatican II is ignored, however, Vatican II documents in all their fuzzy glory are constantly quoted, although they themselves are not binding on the faithful.
The other thing is it has to do with is priestly formation.

Yes, excellent point. This is very true.

One would have to hear the whole talk by Fr. Barreiro, but I think he has a good point. When everything is up for grabs, why should one issue be exempt? If the Church can change the Mass, then why can't they change the teaching on contraception?
