Today is traditionally the celebration of the feast of Corpus Christi , although it is celebrated liturgically  this coming Sunday.  Processions are held anytime during the days surrounding the feast, so today – the Thursday after Trinity Sunday, the traditional date – is a natural.
 

 
Corpus Christ procession today on boats in Seehausen, Germany.
Today the Pope will celebrate Mass at St. John Lateran and then lead a Corpus Christi procession up the hill to St. Maria Maggiore. It will all be broadcast live, both on EWTN and via CTV. You can watch both online.
What about in your area? Any processions this week?
(Fr. Martin Fox blogged on his parishes’ procession in Piqua, Ohio here.)
