Whether the beatified angels advance in beatitude?

❌ Objection 1 : It would seem that the beatified angels can advance in beatitude. For charity is the principle of merit. But there is perfect charity in the angels. Therefore the beatified angels can merit. Now, as merit increases, the reward of beatitude increases. Therefore the beatified angels can progress in beatitude.

❌ Objection 2 : Further, Augustine says (De Doctr. Christ. i) that "God makes use of us for our own gain, and for His own goodness. The same thing happens to the angels, whom He uses for spiritual ministrations"; since "they are all [*Vulg.: 'Are they not all . . . ?'] ministering spirits, sent to minister for them who shall receive the inheritance of salvation" (Heb. 1:14). This would not be for their profit were they not to merit thereby, nor to advance to beatitude. It remains, then, that the beatified angels can merit, and can advance in beatitude.

❌ Objection 3 : Further, it argues imperfection for anyone not occupying the foremost place not to be able to advance. But the angels are not in the highest degree of beatitude. Therefore if unable to ascend higher, it would appear that there is imperfection and defect in them; which is not admissible.
