Answer this: When Lazarus died,
and Our Lord wept, was there anything wrong with that?
Why do we have to seek to act in a way that is rational when it is not heartfelt? Why glorify logic? Why not feel free to feel what we feel and to deal with our emotions openly rather than trying to act “rational”?
Mind you, I think it is not good to “expect” people to feel sad when someone they love dies. Yes, it is also natural and not contrary to real gratitude for the person’s presence in one’s life to
feel happy that they are beyond any suffering except that which will be to their profit and eternal benefit. Of course it is OK to feel joy at the death of a Christian. It is OK to set aside feelings of grief, even. Rationality, though, has nothing to do with any of it. It is not rational, based on what we know about the human person, to try to legislate or deny emotions. In my opinion, that is not the way emotions are mastered, nor how they fulfill the function that Providence intended for them to serve.
If you don’t feel grief when someone you love dies, that is OK. That is a gift, I would think. As for how people feel when you die, I think you will be in a place to allow them to feel what they feel, even if you did want to comfort them with the greater truth of the situation.
I think the most important thing is not to tell those we love how to feel when we die, but to remind them to pray for our perfection. It is not so fashionable as it once was to pray for the Church Suffering, but to think of everyone as either Church Triumphant or Church Militant, with no other third state possible.
