Do Protestants believe that suicides go to Hell?
Your statement covers a lot of ground; my understanding of the Gospel of Christ is once saved, always saved. We mere mortal sinners are imperfect and will continue to sin but the Blood of Christ makes us worthy in His eyes.
No, Protestants don’t believe that suicides go to hell, because there are no sciprtures to support it.
In fact, the scriptures indicate otherwise.
So, Papal bulls and tradition have nothing to do with it.
Consider that suicide is murder. Reference the 5th commandment.
It depends on which person. Protestantism to a large extent is “each person chooses his own path based on his own interpretation (or the pastor he follows)”
