No, this wasn’t a sin. You have a valid reason for missing Mass.
Hey, you guys. This is a Catholic forums, don’t nitpick over spelling or scrupulosity. I’ve done the whole ‘get a new screenname and post questions because of uncertainty.’ Scrupulosity is a form of OCD, it isn’t easy. Some people need to hear that it isn’t sinful a few times before their mind wraps around the mind.
As for Andy_42, he isn’t Catholic. His girl is, he’s trying to understand. A secular mind is both interested, frightened and trying to accept the divine rules of the Catholic Church. Being told everything you believe is sinful, possibly mortally so, is a big thing to grasp.
There’s a whole other thread where someone wrote about a Eucharistic Minister who they believe is in mortal sin. Everyone jumped on the OP and told them not to judge unless they are certain or have seen the offense. Well here’s your own advice in return: Don’t judge unless you are certain. So what if it’s a troll? You fed it- maybe someone else with a similar question who isn’t a troll will see it. Or it isn’t a troll at all, just someone awkward with the computer or with words. Always assume the best, treat with kindness and with charity. Jesus didn’t give the woman caught in adultery a long rant about how she should have known better, questioned her intelligence, or make a comment about how she sounds like the other sinner down the street. He saved her from stoning, and then told her to sin no more.
Apologies for off-topic rant.
