Whether there can be strife or discord among the angels?

Objections

Objection 1 : It would seem that there can be strife or discord among the angels. For it is written (Job 25:2): "Who maketh peace in His high places." But strife is opposed to peace. Therefore among the high angels there is no strife.
Objection 2 : Further, where there is perfect charity and just authority there can be no strife. But all this exists among the angels. Therefore there is no strife among the angels.
Objection 3 : Further, if we say that angels strive for those whom they guard, one angel must needs take one side, and another angel the opposite side. But if one side is in the right the other side is in the wrong. It will follow therefore, that a good angel is a compounder of wrong; which is unseemly. Therefore there is no strife among good angels.
