Death, dying, and funerals · Question 8
If someone dies by suicide, are they denied a funeral and any hope of salvation?

The question: “Is it true that anyone who takes their own life goes straight to hell and that the Church refuses them a funeral?”
The Church's answer: Suicide is a grave matter, contrary to life, but the Church does not read a person's eternal destiny off that act alone. Grave psychological disturbance, extreme anguish and fear, and suffering can diminish someone's responsibility. God alone fully knows what was inside them and what their last moment held. The Catechism teaches that we should not despair of the eternal salvation of those who have taken their own lives, that by ways known to him alone God can provide the opportunity for the repentance that leads to salvation, and that the Church prays for them.
Canon law, too, does not list the bare fact of a suicide among the grounds that automatically refuse a funeral. As a rule the faithful are to be given a church funeral, and whether some grave circumstance in canon law would restrict one in a particular case is judged by the parish pastor and the local ordinary. No one may hold the family responsible for the death, or publicly condemn the person who died at the funeral.
If they press further: “If I start having thoughts of wanting to die, do I have to confess it as a sin first?” — don't stay alone right now; tell an adult you trust immediately. Get away from dangerous objects and places, and ask for help from your local emergency number, a suicide-prevention or crisis support service, and medical staff. Prayer and confession can help, but they never take the place of urgent safety measures and treatment.
In one sentence: “Suicide is a grave matter, but we don't despair of the person's salvation or pronounce them condemned. The Church prays for them, cares for the family, and connects anyone in crisis to people and professional services right away.”
