It can be fairly said that the Vatican tends to be out of date and a bit pedantic, and not just about language.  It is a male institution, with a narrow perspective.  There is a lack of sensitivity  about  usage, as shown by the unpopular and unnecessary liturgy changes Pope Benedict instituted and by his unfortunate Muslim comments early on in his reign.  There has also been a lack of sensitivity and awareness about sexual abuse by priests, bishops and cardinals.  

It can also be fairly said that the church needs much more input from women--overall and not just about language.
