Whether angels are appointed to the guardianship of all men?

Objections

Objection 1 : It would seem that angels are not appointed to the guardianship of all men. For it is written of Christ (Phil. 2:7) that "He was made in the likeness of men, and in habit found as a man." If therefore angels are appointed to the guardianship of all men, Christ also would have had an angel guardian. But this is unseemly, for Christ is greater than all the angels. Therefore angels are not appointed to the guardianship of all men.
Objection 2 : Further, Adam was the first of all men. But it was not fitting that he should have an angel guardian, at least in the state of innocence: for then he was not beset by any dangers. Therefore angels are not appointed to the guardianship of all men.
Objection 3 : Further, angels are appointed to the guardianship of men, that they may take them by the hand and guide them to eternal life, encourage them to good works, and protect them against the assaults of the demons. But men who are foreknown to damnation, never attain to eternal life. Infidels, also, though at times they perform good works, do not perform them well, for they have not a right intention: for "faith directs the intention" as Augustine says (Enarr. ii in Ps. 31). Moreover, the coming of Antichrist will be "according to the working of Satan," as it is written (2 Thess. 2:9). Therefore angels are not deputed to the guardianship of all men.
