I help direct some chess tournaments. Coming up is one that’s going to take place over multiple days and by working it I know I won’t be able to make Mass on the Sunday of the tournament. (Starts early, ends late, and I won’t have my own transportation.) Now I understand from what I’ve read that due to valid reasons, it isn’t sinful to miss Mass that weekend.
My question then is if I need to ask a priest for a disspensation (I’m not really familiar with them or when they’re needed) or if I’m fine without one.
