Note, he is an Evangelical apologist, and his answer is "no, not as the word means today", given here:
The tekton ticker : Did Jesus Commit Suicide?
But his answer is at best incomplete. Here is my comment, which he might or might not chose to publish:
|"While there were undoubtedly mentally unstable people who killed themselves in the ancient world, suicide was more widely perceived as a noble way to die under certain specific circumstances. The samuari warrior, the Roman gladiator, and the Greek philosopher Socrates might all be viewed in these terms."
Sigh "the ancient world" ...
Now, up to recently, one was not really in the habit of saying "In our daily experience, "suicide" comes with specific associations: A person who is mentally unstable, depressed, or otherwise in some sort of mentally or spiritually undesirable state."
The only thing there is spiritually undesirable state, namely mortal sin.
Usually other ones, like sorrow, leading up to it.
But giving suicides the excuse from crime given by excuse of insanity was not done. If English police found a man trying to hang himself, he would be saved, brought to trial, and executed for the crime of attempted suicide.
Hopefully having, in the meantime, had some time to make his peace with God, before the death date he was not chosing himself.
However, Stoics did admire the suicide of Socrates. And extended the cases when suicide was permissible in their distorted view. And as Apologists we must not only defend the Honour of God against the charge of having been unstable, but also against the charge of having been a Stoic.
