Deuterocanon

Sirach 3:26

Ben Sira, Ecclesiasticus

25 Without eyes there is no light; without knowledge there is no wisdom. 26 A stubborn mind will fare badly at the end, and whoever loves danger will perish in it. 27 A stubborn mind will be burdened by troubles, and the sinner adds sin to sins. 28 When calamity befalls the proud, there is no healing, for an evil plant has taken root in him. 29 The mind of the intelligent appreciates proverbs, and an attentive ear is the desire of the wise.

Augustine City of God 1.27

On the City of God Against the Pagans

There remains one reason for suicide which I mentioned before, and which is thought a sound one — namely, to prevent one's falling into sin either through the blandishments of pleasure or the violence of pain. If this reason were a good one, then we should be impelled to exhort men at once to destroy themselves, as soon as they have been washed in the laver of regeneration, and have received the forgiveness of all sin. Then is the time to escape all future sin, when all past sin is blotted out. And if this escape be lawfully secured by suicide, why not then specially? Why does any baptized person hold his hand from taking his own life? Why does any person who is freed from the hazards of this life again expose himself to them, when he has power so easily to rid himself of them all, and when it is written, He who loves danger shall fall into it? Why does he love, or at least face, so many serious dangers, by remaining in this life from which he may legitimately depart?
