It is the Priest's job to point out that suicide is a grievous sin. This may be upsetting to some of the Celebrate Life folks, but it is true, nonetheless.
Is suicide by someone mentally incompetent a grievous sin?
If not, how do you calibrate when mental illness is not sufficient for forgiveness? In such a gray area, the priests should confine their condemnations to regular church services and in a generalized manner. Trotting it out at a funeral assumes they knew the mental health of the individual. Otherwise, it’s insensitive, arrogant inconsideration.
Spot on. Really sad what happened, but true nonetheless. He probably could have said something to the effect that suicide is not the way to go and to seek help if one were considering that and let it go. Sounds like he was a bit harsh. A bigger question here is the parents' failure to teach the son that suicide was not the solution to anything. THEY should be criticized.
