Consequently, then, those Religious Orders are in the highest rank which are devoted to teaching and preaching. And these, too, approach most nearly to the perfection of the Episcopate; just as in other things, too, the ends of those in the first place are, as S. Denis says, close knit to the principles of those in the second place.[494] The second rank is occupied by those Orders which are devoted to contemplation. And the third with those devoted to external works. And in each of these grades there is a certain superiority according as one Order aims at acts of a higher order than does another, though of the same class. Thus in the works of the active life it is a greater thing to redeem captives than to receive guests; in the contemplative life, too, it is a greater thing to pray than to study. There may also be a certain superiority in this that one is occupied with more of such works than another; or again, that the rules of one are better adapted to the attainment of their end than are those of another. Some, however, maintain that the contemplative Orders are not superior to the active Orders, thus: 1. In the Canon Law[495] it is said: "Since the greater good is to be preferred to the less, so, too, the common gain is to be preferred to private gain; and in this sense teaching is rightly preferred to silence, anxious care for others to contemplation, and toil to repose." But that Religious Order is the better which is directed to the attainment of the greater good. Hence it seems that Orders which are devoted to an active life are superior to those which aim solely at contemplation. But this Decretal speaks of the active life as concerned with the salvation of souls. 2. All Religious Orders aim at the perfection of charity. But on those words in the Epistle to the Hebrews,[496] _Ye have not yet resisted unto blood_, the Gloss has: "There is no more perfect charity in this life than that to which the holy Martyrs attained, for they strove against sin even _unto blood_." But to strive _unto blood_ belongs to the Military Religious Orders, and they lead an active life. It would seem, then, that these latter are the highest form of Religious Order. But these Military Orders are more concerned with shedding the blood of their enemies than with shedding their own, which is the feature of the Martyrs. At the same time, there is nothing to preclude these Religious from at times winning the crown of martyrdom and thus attaining to a greater height than other Religious; just as in some cases active works are to be preferred to contemplation. 3. Lastly, the stricter an Order the more perfect it seems to be. But there is nothing to preclude active Orders from being stricter in their observance than some contemplative Orders.
