The Synod does not have an official position regarding the eternal state of individuals who have committed suicide, though theologians of the Synod have commented from time to time on pastoral questions that often arise in such cases.
Since the spiritual condition of an individual upon death is known only to God, our theologians have proceeded cautiously in making judgments in this regard. LCMS pastor and author Otto E. Sohn, for example, has stated:
"Assuredly we would not wish to judge anyone who resorts to self-destruction. It is impossible for us to plumb the depths of gloom into which even Christian people may sink and irresponsibly lay unholy hands upon themselves. Perhaps the Lord will not hold them responsible, but we do not know." (What's the Answer, CPH, 1960, p. 144).
In one of his Table Talks, Martin Luther himself commented: "I don't have the opinion that suicides are certainly to be damned. My reason is that they do not wish to kill themselves but are overcome by the power of the devil." Luther goes on, however, to express concern that this statement not be misunderstood or misused in a way that would downplay the danger and seriousness of this sin in the minds of people (Luther's Works, American Edition, Vol. 54, p. 29).
