Title question. Is there something in Canon Law or the GIRM that states who masses can be requested for. I'm thinking specifically if mass can be requested for non-Catholics. I now that we can offer our individual intentions for anyone, but can just as an example a mass be named and offered for the repose of the soul of a friend who was an atheist that died in a car accident. Or a member of a Baptist church that died after a long illness? Or a close friend that is currently struggling with trying to find truth in religion?
I'm looking for something specific in Canon Law or some other official Church teaching.
