Positive and direct suicide perpetrated without God's consent always constitutes a grave injustice towards Him. To destroy a thing is to dispose of it as an absolute master and to act as one having full and independent dominion over it; but man does not possess this full and independent dominion over his life, since to be an owner one must be superior to his property. God has reserved to himself direct dominion over life; He is the owner of its substance and He has given man only the serviceable dominion, the right of use, with the charge of protecting and preserving the substance, that is, life itself. Consequently suicide is an attempt against the dominion and right of ownership of the Creator.
To this injustice is added a serious offence against the charity which man owes to himself, since by his act he deprives himself of the greatest good in his possession and the possibility of attaining his final end. Moreover, the sin may be aggravated by circumstances, such as failure in conjugal, paternal, or filial piety, failure in justice or charity, if by taking his life one eludes existing obligations of justice or acts of charity, which he could and should perform.
That suicide is unlawful is the teaching of Holy Scripture and of the Church, which condemns the act as a most atrocious crime and, in hatred of the sin and to arouse the horror of its children, denies the suicide Christian burial. Moreover, suicide is directly opposed to the most powerful and invincible tendency of every creature and especially of man, the preservation of life. Finally, for a sane man deliberately to take his own life, he must, as a general rule, first have annihilated in himself all that he possessed of spiritual life, since suicide is in absolute contradiction to everything that the Christian religion teaches us as to the end and object of life and, except in cases of insanity, is usually the natural termination of a life of disorder, weakness, and cowardice.
Positive but indirect suicide committed without Divine consent is also unlawful unless, everything considered, there is sufficient reason for doing what will cause death to follow. Thus, it is not a sin, but an act of exalted virtue, to go into savage lands to preach the Gospel, or to the bedside of the plague stricken, to minister to them, although they who do so have before them the prospect of inevitable and speedy death; nor is it a sin for workmen in the discharge of duties to climb on roofs and buildings, thus exposing themselves to danger of death, etc. All this is lawful precisely because the act itself is good and upright, for in theory the persons in question have not in view either as end or means the evil result, that is, death, that will follow, and, moreover, if there be an evil result it is largely compensated for by the good and useful result which they seek.
On the other hand there is sin in exposing oneself to danger of death to display courage, to win a wager, etc., because in all these cases the end does not in any way compensate for the danger of death that is run. To judge whether or not there is sufficient reason for an act which will apparently be followed by death, all the circumstances must be weighed, namely, the importance of the good result, the greater or less certainty of its being attained, the greater or less danger of death, etc., all questions which may in a specific case be very difficult to solve.
If a man as usufructuary is obliged in justice to preserve his life, it follows that he is equally bound to make use of all the ordinary means which are indicated in the usual course of things, namely:
he should employ all the ordinary means which nature itself provides, such as to eat, drink, sleep, and so on.
he should avoid all dangers which he may easily avoid, e.g. to flee from a burning house, to escape from an infuriated animal.
In fact to neglect the ordinary means for preserving life is equivalent to killing one's self, but the same is not true with regard to extraordinary means. Thus theologians teach that one is not bound in order to preserve life to employ remedies which, considering one's condition, are regarded as extraordinary and involving extraordinary expenditure; one is not obliged to undergo a very painful surgical operation, nor a considerable amputation, nor to go into exile in order to seek a more beneficial climate, etc. To use a comparison, the lessee of a house is bound to take care of it as becomes a good father of a family, to make use of the ordinary means for the preservation of the property, for instance, to extinguish a fire which he may easily extinguish, etc., but he is not bound to employ means considered extraordinary, such as to procure the latest novelties invented by science to prevent or extinguish fire.
The plague of suicide belongs especially to the period of decadence of the civilized peoples of antiquity, Greeks, Romans, and Egyptians. The Christian Middle Ages were unacquainted with this morbid tendency, but it has reappeared at a more recent period, has developed constantly since the Renaissance, and at present has reached such an intensity among all civilized nations that it may be considered one of the special evils of our time.
Religion alone, and especially the Catholic religion, instructs us with regard to the true destiny of life and the importance of death; it alone furnishes a solution of the enigma of suffering, inasmuch as it shows man living in a land of exile and suffering as a means of acquiring the glory and happiness of a future life. By its doctrines of the efficacy of repentance and the practice of confession it relieves the moral suffering of man; it forbids and prevents to a large extent the disorders of life; in a word it is of a nature to prevent the causes which are calculated to impel a man to the extreme act.
