Can you go to heaven if you commit sucide and you are of sound mind?
First, I want to make sure that all people reading this know that there is help available for suicidal feelings. Here are some resources that may prove helpful to anyone who feels tempted to harm himself:
Web address: suicidehotlines.com/
Phone: 1-800-SUICIDE (1-800-784-2433)
If you need pastoral support, Catholic answers to moral questions, or the prayers of our staff, please feel free to call Catholic Answers. We are open Monday thru Friday, 9 AM to 5 PM Pacific time. The phone number is 619-387-7200.
Second, the answers in these links should explain the difference between grave matter and mortal sin as it pertains to suicide. If you have any further questions or concerns that are not answered by these links, please contact Catholic Answers directly.
