Telling someone they are going to hell: religious Duty or Not your place to say?
Quite frankly, neither. It is not a very useful teaching, and its drawbacks far outweight any constructive use.
Many religions claim that their adherents are going to heaven, and the non believers are going to hell. Abrahamic religions have pushed this but even eastern religions believe this even.
I suppose that is true to some extent, but I don't think it is well regarded among any non-Abrahamic believers I ever met.
My take on this is if someone tells me that I am going to hell, then it is my fundamental argument that a persons virtues is determined by his actions on earth.
The audacity of a person telling me going to hell makes me wonder who gave them the right to tell me. I am not a walk away type of person so it would be difficult for me to reason with an animal like that.
Any thoughts?
Diagnosting someone as "hell-bound" is indeed a display of lack of consideration, or perhaps a sincere worry (albeit still curious). It will depend on the attitude, but it is never comendable.
It is however wise to try and determine what led one to say you such things. Some people are sincere and well-meaning when they say such things, and those deserve a bit of gentleness when dealt with.
Others, however, are hypocritical thugs in denial and may well deserve rude words. It is important to talk to people at the level and language that they accept and understand.
