1 Objection 1: It would seem that there are no orders among the demons. For order belongs to good, as also mode, and species, as Augustine says De Nat. Boni iii); and on the contrary, disorder belongs to evil. But there is nothing disorderly in the good angels. Therefore in the bad angels there are no orders.
1 Ad primum sic proceditur. Videtur quod ordines non sint in Daemonibus. Ordo enim pertinet ad rationem boni, sicut et modus et species, ut Augustinus dicit in libro de natura boni; et e contrario inordinatio pertinet ad rationem mali. Sed in bonis Angelis nihil est inordinatum. Ergo in malis Angelis non sunt aliqui ordines.
2 Objection 2: Further, the angelic orders are contained under a hierarchy. But the demons are not in a hierarchy, which is defined as a holy principality; for they are void of all holiness. Therefore among the demons there are no orders.
2 Praeterea, ordines angelici sub aliqua hierarchia continentur. Sed Daemones non sunt sub aliqua hierarchia, quae est sacer principatus, cum ab omni sanctitate sint vacui. Ergo in Daemonibus non sunt ordines.
3 Objection 3: Further, the demons fell from every one of the angelic orders; as is commonly supposed. Therefore, if some demons are said to belong to an order, as falling from that order, it would seem necessary to give them the names of each of those orders. But we never find that they are called Seraphim, or Thrones, or Dominations. Therefore on the same ground they are not to be placed in any other order.
3 Praeterea, Daemones de singulis ordinibus Angelorum ceciderunt, ut communiter dicitur. Si ergo aliqui Daemones dicuntur esse alicuius ordinis, quia de illo ordine ceciderunt; videtur quod deberent eis attribui nomina singulorum ordinum. Nunquam autem invenitur quod dicantur Seraphim, vel throni, vel dominationes. Ergo, pari ratione, non sunt in aliquibus ordinibus.
4 On the contrary, The Apostle says Eph. 6, 12): Our wrestling... is against principalities and powers, against the rulers of the world of this darkness.
4 Sed contra est quod apostolus dicit, ad Ephes. ult., quod est nobis colluctatio adversus principes et potestates, adversus mundi rectores tenebrarum harum.
5 I answer that, As explained above Question 108, Articles 4, 7, 8), order in the angels is considered both according to the grade of nature; and according to that of grace. Now grace has a twofold state, the imperfect, which is that of merit; and the perfect, which is that of consummate glory. If therefore we consider the angelic orders in the light of the perfection of glory, then the demons are not in the angelic orders, and never were. But if we consider them in relation to imperfect grace, in that view the demons were at the time in the orders of angels, but fell away from them, according to what was said above Question 62, Article 3), that all the angels were created in grace. But if we consider them in the light of nature, in that view they are still in those orders; because they have not lost their natural gifts; as Dionysius says Div. Nom. iv).
5 Respondeo dicendum quod, sicut iam dictum est, ordo angelicus consideratur et secundum gradum naturae, et secundum gradum gratiae. Gratia vero habet duplicem statum, scilicet imperfectum, qui est status merendi; et perfectum, qui est status gloriae consummatae. Si ergo considerentur ordines angelici quantum ad perfectionem gloriae, sic Daemones neque sunt in ordinibus angelicis, neque unquam fuerunt. Si autem considerentur quantum ad id quod est gratiae imperfectae, sic Daemones fuerunt quidem aliquando in ordinibus Angelorum, sed ab eis ceciderunt; secundum illud quod supra posuimus, omnes Angelos in gratia creatos fuisse. Si autem considerentur quantum ad id quod est naturae, sic adhuc sunt in ordinibus, quia data naturalia non amiserunt, ut Dionysius dicit.
6 Reply to Objection 1: Good can exist without evil; whereas evil cannot exist without good Question 49, Article 3); so there is order in the demons, as possessing a good nature.
6 Ad primum ergo dicendum quod bonum potest inveniri sine malo; sed malum non potest inveniri sine bono, ut supra habitum est. Et ideo Daemones, inquantum habent naturam bonam, ordinati sunt.
7 Reply to Objection 2: If we consider the ordering of the demons on the part of God Who orders them, it is sacred; for He uses the demons for Himself; but on the part of the demons' will it is not a sacred thing, because they abuse their nature for evil.
7 Ad secundum dicendum quod ordinatio Daemonum, si consideretur ex parte Dei ordinantis, est sacra, utitur enim Daemonibus propter seipsum. Sed ex parte voluntatis Daemonum, non est sacra, quia abutuntur sua natura ad malum.
8 Reply to Objection 3: The name Seraphim is given from the ardor of charity; and the name Thrones from the Divine indwelling; and the name Dominations imports a certain liberty; all of which are opposed to sin; and therefore these names are not given to the angels who sinned.
8 Ad tertium dicendum quod nomen Seraphim imponitur ab ardore caritatis, nomen autem thronorum ab inhabitatione divina, nomen autem dominationum importat libertatem quandam, quae omnia opponuntur peccato. Et ideo peccantibus Angelis huiusmodi nomina non attribuuntur.
