(a) when one is unconcerned whether evil results or not, or desires that it may result (e.g., when a person who is tired of life seeks a dangerous occupation for the diversion and excitement it affords, or when a person practises abstinence from certain remedies as an act of moderate mortification);
(b) when one does not wish the evil result, but is so stupid or rash as to believe that an imprudent risk can be taken and evil escaped through chance or good luck, as when a student goes up for a difficult examination with slight preparation, trusting that only the things he knows will be asked.
2304. Refusal of Medicine or Hygienic Care.—(a) If there is a sufficient reason for this conduct, no sin is committed. There may be sufficient reasons of a natural kind (e.g., that the remedies are harmful or useless or too expensive), or of a supernatural kind (e.g., St. Agatha refused all medicines because God Himself was her physician, certain Saints were divinely inspired to make no effort to remove bodily maladies on account of the spiritual profit derived from them).
(b) If there is no sufficient reason for this conduct, it is sinful. Thus, one sins against faith, if the reason for the conduct is disbelief in the existence of evil (e.g., Christian Science or Eddyism attributes sickness and pain to imagination, and says that the only cure is “faith”); one sins by temptation of God, if the reason for the conduct is vain expectation of miracles; one is guilty of suicide or homicide, if the purpose is to end life, etc.
2305. The Sinfulness of Temptation of God.—(a) To doubt the perfections of God, or to call upon the extraordinary Providence of God in disregard of the ordinary Providence He has established is the essence of temptation of God. It is sinful, because it includes either unjustifiable doubt or vincible ignorance in the intellect or presumption in the will. Hence the command given in Deuteronomy (vi. 16): “Thou shalt not tempt the Lord thy God.” But invincible ignorance excuses from sin, and hence many of those who in times past resorted to ordeals by painful or dangerous tests (e.g., walking on burning coals, risking death in deep waters), in order that God might settle a doubtful matter, were, on account of their good faith, guiltless of temptation of God. The practice was condemned by the Church in the ninth century.
(b) To doubt about the positive and unknown will of God, or to call upon the extraordinary Providence of God (i.e., the direct intervention of the First Cause), without disregard of the ordinary Providence (i.e., of second causes appointed by God), is not sinful, if it is justified by necessity. Thus, being unable to resist the nations leagued against him, Josaphat prayed: “As we know not what to do, we can only turn our eyes to Thee” (II Paral., xx. 12). And Our Lord promised the disciples that, when they should be unable to prepare their defense on account of the persecutions to which they were subjected, the Spirit Himself would speak through them (Matt., X. 19), and that He would enable them to do things as difficult as moving mountains when real necessity called for it (Matt., xvii. 19). It is not unbelief to doubt about matters pertaining to God that are really doubtful (i.e., not His perfections, but His positive and unknown will), and hence one does not tempt God who asks for divine guarantees of a religion proposed as divinely revealed (see 795); it is not presumption to ask God for a sign or proof, if God directs one to do this (e.g., Abraham in Gen., xv. 8, was inspired to seek a sign that the promised land would be given his posterity; Achaz in Isaias, vii. 11, was bidden for the sake of others to ask for a sign), or if, when a sign from God seems necessary or very useful, one prays for it prudently and on condition that the request is pleasing to God (e.g., the Apostles in Acts, iv. 30, prayed for signs and wonders in confirmation of their preaching).
2306. The Malice of Temptation of God.—(a) It is a sin directly against religion, for one shows contempt to God when one demands that He prove His perfections, or when one takes the liberty to disregard the ordinary means He has established and to call for others. The sin is less, however, than that of superstition, since temptation of God professes doubt, while superstition professes positive error. Temptation of God offends also against other virtues, such as faith (e.g., when one doubts the perfections of God), hope (e.g., when one presumes that God will do all without one’s cooperation), charity (e.g., when a person exposes his own life to risk or his neighbor to scandal in a vain confidence that the danger will be miraculously averted).
(b) It is a mortal sin from its nature, since it offends religion. But it may be venial on account of the imperfection of the act, as when from weakness of faith or without reflection one asks unnecessarily for a sign (Luke, i. 11-20). It may be venial also from the lightness of the matter, if the temptation is interpretative, as when one presumes on the divine aid in a slight sickness, an unimportant talk, or other small affair.
2307. As a rule temptation of God is only a venial sin, and in an individual case it is rarely mortal, except in the following instances:
(a) when one intends a grave offense against God, as by doubting His goodness, demanding or attempting a miracle to satisfy curiosity;
