I didn't read the doc......BUT:The feast of the Cross is 3 days, tout 17-19. only if Tout 17 falls to be sunday, does it break the rite of sunday. otherwise, the feast doesn't change the sunday rite......if tout 18 or 19 falls on sunday, they don't change sunday rite.....This year. the feast is Thursday, Friday and Saturday.....that's it. It doesn't effect sunday.
