Steadfastness, Effeminacy and Pertinacity
Steadfastness
Steadfastness.—Steadfastness is a virtue which is so devoted to the goodness of continuing in the right that it is not fatigued by the length of time or the repeated effort required for a good work (virtue of persistence or perseverance), nor disheartened by the opposition which a good work encounters (virtue of manliness or constancy), but goes on unmoved until the conclusion which right reason calls for has been arrived at.
(a) The Virtue.—Steadfastness belongs to fortitude, since the essence of both is a struggle against difficulty; but steadfastness is the inferior, since it is nobler and more heroic to be undismayed by the peril of death than to be unconquered by strain of monotony or opposition. Steadfastness is a most important virtue, for it avails one little to begin a work well if it is not carried to a successful conclusion. Without it one puts hand to the plow but looks back (Luke, ix. 62), or begins to build but does not finish (Like, xiv. 30); with it the work begun is crowned, the harvest will be reaped (Gal., vi. 9, 10), and salvation secured (Matt., x. 22). Scripture abounds with exhortations to steadfastness (I Cor., xv. 58; Phil., iv. i; II Tim., iii. 13; Ecclus., xi. 21, 22, v. 12; John, viii. 31; Heb., xii. 7); but final perseverance is a special gift of God (I Peter, v. 10).
(b) The Opposite Vices.—Opposed to steadfastness by deficiency is the vice of effeminacy or weakness, by excess the vice of pertinacity. The effeminate person, lacking stamina to go on in a necessary good, surrenders to weariness or opposition by abandoning the undertaking or by taking up with evil (Matt., xi. 7, 8). The pertinacious person continues in the course he has begun when right reason bids him to discontinue, as when one has taken a vow and does not wish to accept the dispensation which a change of circumstances necessitates. These sins are venial unless they go counter to a grave duty, as when an effeminate person gives up the resolution to avoid a very dangerous occasion of sin, or the headstrong person determines to fast during the remainder of Lent when this will seriously injure his health.
