("borrowed" from Fr. Z's post)
I celebrated this wonderful day by attending Mass... In the Extraordinary Form! ;)
In short, Summorum Pontificum 7 years ago pretty much gave the OK to almost any priest, anytime, anywhere, to celebrate the Extraordinary Form of the Roman Rite (Latin Mass, Old Form, Tridentine Mass, whatever you want to call it).
If you don't have an EF near you (that's in communion. SSPX = spiritually icky), wave a copy of SP in front of your pastor and mail him another copy. And send another copy via email in case the postman took it to read for himself. And text him the link if you have to. Get him to read it and then pray that it inspires him to say the Old Form, even if it's just once a week...
Have a blessed day!
