Making use of the parish bulletin!
Regarding B), I'm thrilled beyond belief that it seems to be finally coming, and find it very funny that I will be in Ireland actually when it comes (if it does indeed come on the most perfect day - 7/7/7!) I'll let you know what the Irish reaction is as I witness it. :)
I think that it would be a wonderful idea for all pastors and parishes to really USE the weekly bulletin for once, to catechize and prepare people for what this Motu Proprio really means to the "Catholic in the pew". Here is a wonderful article that a pastor is using to do just that! I encourage all of you who work in parishes to take a look at it, and see if your parish might want to use Fr. Fox's text (I'm sure he wouldn't mind - but perhaps you should ask first) or adapt it to craft your own bulletin article. Those of us who aren't pastors or parish employees could also just send the link to his article around your e-mail lists, your "virtual parish", so that proper basic information on this decision by the Holy Father can be made known more clearly.
