The pastors at our parish have pointedly said that not only is there a dispensation for staying home when you are sick but that if you are sick your pastor is telling you up front: STAY HOME!! He says this to protect frail parishioners who deserve to be able to have a common-sense amount of safety from communicable diseases. For you, maybe you miss Mass once. For them, maybe their health is knocked down and they’re never going to get to come again. Don’t be a “hero” who puts other people on the line more than yourself.
There was a similar prohibition suggested for people who can barely walk who insist on showing up when there is an ice storm. It was a suggestion, but the message was: Don’t even bother to ask me, this is what I’m telling you now, and it is not a difficult question to answer.
He did imply that sometimes the most faithful parishioners are also the most difficult ones to persuade to use their common sense. Perseverance, like all virtues, must be good friends with Wisdom.
