Corpus Christi

Discussions yesterday and today about the Corpus Christi have prompted this post.

Your opinion is sought on when the feast of Corpus Christi should be celebrated? On the Thursday or the Sunday following (ie. the 2nd Sunday after Pentecost)?

The Vatican of course celebrated the great feast on the Thursday, as we see here (thanks to American Papist), but in many countries the feast was celebrated (as well as the procession) on the Sunday even prior to 1962.



There are 3 options I think:
1) Both the Mass of Corpus Christi and Procession on Thursday
2) Mass of Corpus Christi on Thursday an Procession on Sunday
3) Both the Mass and Procession on Sunday

Then there is also the argument whether Corpus Christi is a Holy Day of Obligation still and whether if you are normally a Tridentine Rite Mass goer and miss the Thursday Corpus Christi, should you attend the Novus Ordo on the Sunday to ensure you attend a Corpus Christi Mass...
