I know that there are valid reasons to miss mass for illness/care of an infant, but I know that travel is not one of the them. Where ever you travel, most likely there is a catholic church around…you just need to look first. From what I understand, going to frequent Mass is a good thing, but going to Mass on Sunday is the day of obligation. So no, your attendance to mass on Friday doesn’t suffice for Sunday Mass you missed. If I am incorrect, please feel free to correct me…I didn’t have time to reference the CC before posting.
