On the contrary, Augustine (De Sanct. Virgin. xlvi) prefers martyrdom to virginity which pertains to perfection. Therefore martyrdom seems to belong to perfection in the highest degree.
I answer that, We may speak of an act of virtue in two ways. First, with regard to the species of that act, as compared to the virtue proximately eliciting it. In this way martyrdom, which consists in the due endurance of death, cannot be the most perfect of virtuous acts, because endurance of death is not praiseworthy in itself, but only in so far as it is directed to some good consisting in an act of virtue, such as faith or the love of God, so that this act of virtue being the end is better.
A virtuous act may be considered in another way, in comparison with its first motive cause, which is the love of charity, and it is in this respect that an act comes to belong to the perfection of life, since, as the Apostle says (Col. 3:14), that "charity . . . is the bond of perfection." Now, of all virtuous acts martyrdom is the greatest proof of the perfection of charity: since a man's love for a thing is proved to be so much the greater, according as that which he despises for its sake is more dear to him, or that which he chooses to suffer for its sake is more odious. But it is evident that of all the goods of the present life man loves life itself most, and on the other hand he hates death more than anything, especially when it is accompanied by the pains of bodily torment, "from fear of which even dumb animals refrain from the greatest pleasures," as Augustine observes (QQ. 83, qu. 36). And from this point of view it is clear that martyrdom is the most perfect of human acts in respect of its genus, as being the sign of the greatest charity, according to John 15:13: "Greater love than this no man hath, that a man lay down his life for his friends."
Reply Obj. 1: There is no act of perfection, which is a matter of counsel, but what in certain cases is a matter of precept, as being necessary for salvation. Thus Augustine declares (De Adult. Conjug. xiii) that a man is under the obligation of observing continency, through the absence or sickness of his wife. Hence it is not contrary to the perfection of martyrdom if in certain cases it be necessary for salvation, since there are cases when it is not necessary for salvation to suffer martyrdom; thus we read of many holy martyrs who through zeal for the faith or brotherly love gave themselves up to martyrdom of their own accord. As to these precepts, they are to be understood as referring to the preparation of the mind.
Reply Obj. 2: Martyrdom embraces the highest possible degree of obedience, namely obedience unto death; thus we read of Christ (Phil. 2:8) that He became "obedient unto death." Hence it is evident that martyrdom is of itself more perfect than obedience considered absolutely.
Reply Obj. 3: This argument considers martyrdom according to the proper species of its act, whence it derives no excellence over all other virtuous acts; thus neither is fortitude more excellent than all virtues. _______________________
FOURTH ARTICLE [II-II, Q. 124, Art. 4]
Whether Death Is Essential to Martyrdom?
Objection 1: It seems that death is not essential to martyrdom. For Jerome says in a sermon on the Assumption (Epist. ad Paul. et Eustoch.): "I should say rightly that the Mother of God was both virgin and martyr, although she ended her days in peace": and Gregory says (Hom. iii in Evang.): "Although persecution has ceased to offer the opportunity, yet the peace we enjoy is not without its martyrdom, since even if we no longer yield the life of the body to the sword, yet do we slay fleshly desires in the soul with the sword of the spirit." Therefore there can be martyrdom without suffering death.
Obj. 2: Further, we read of certain women as commended for despising life for the sake of safeguarding the integrity of the flesh: wherefore seemingly the integrity of chastity is preferable to the life of the body. Now sometimes the integrity of the flesh has been forfeited or has been threatened in confession of the Christian faith, as in the case of Agnes and Lucy. Therefore it seems that the name of martyr should be accorded to a woman who forfeits the integrity of the flesh for the sake of Christ's faith, rather than if she were to forfeit even the life of the body: wherefore also Lucy said: "If thou causest me to be violated against my will, my chastity will gain me a twofold crown."
