Whether martyrdom is an act of the greatest perfection?

Objections

Objection 1 : It seems that martyrdom is not an act of the greatest perfection. For seemingly that which is a matter of counsel and not of precept pertains to perfection, because, to wit, it is not necessary for salvation. But it would seem that martyrdom is necessary for salvation, since the Apostle says (Rm. 10:10), "With the heart we believe unto justice, but with the mouth confession is made unto salvation," and it is written (1 Jn. 3:16), that "we ought to lay down our lives for the brethren." Therefore martyrdom does not pertain to perfection.
Objection 2 : Further, it seems to point to greater perfection that a man give his soul to God, which is done by obedience, than that he give God his body, which is done by martyrdom: wherefore Gregory says (Moral. xxxv) that "obedience is preferable to all sacrifices." Therefore martyrdom is not an act of the greatest perfection.
Objection 3 : Further, it would seem better to do good to others than to maintain oneself in good, since the "good of the nation is better than the good of the individual," according to the Philosopher (Ethic. i, 2). Now he that suffers martyrdom profits himself alone, whereas he that teaches does good to many. Therefore the act of teaching and guiding subjects is more perfect than the act of martyrdom.
