At least it seems like it these days. A quick read of the obituaries (a habit of paramedics; we like to know how our patients fared) shows a multitude of alternate funeral services where the deceased, especially if they were a young adult, are laid to rest in a service held from a community hall rather than a church. And invariably, there will be a poem at the bottom of the obituary that guarantees the deceased is in heaven, waiting joyfully to be reunited with their loved ones. The simple fact that the funeral is held in a community hall signifies that the person probably didn't have religion in their life, and may have never even been baptized.
So why is it that someone who knows no religion is presumed by his relatives to be in heaven? Well, I guess it's a lot easier on them than wondering if their dearly beloved is suffering eternal hellfire. Or maybe they just don't believe in hell or the consequences of sin. But they clearly believe in the mercy of God, as evidenced by the presumption of heaven for their loved ones.
Sometimes it's just so hard to be Catholic.
