Ambrose of Milan

For it is elsewhere said, that all power is from God. (Rom. 13:1.) Therefore from God’s hands comes the disposal of power, the lust of power is from the evil one; power is not itself evil, but he who evilly uses it. What then; is it good to exercise power, to desire honour? Good if it is bestowed upon us, not if it is seized. We must distinguish however in this good itself. There is one good use of the world, another of perfect virtue. It is good to seek God; it is a good thing that the desire of becoming acquainted with God should be hindered by no worldly business. But if he who seeks God, is from the weakness of the flesh, and the narrowness of his mind, often tempted, how much more is he exposed who seeks the world? We are taught then to despise ambition, because it is subject to the power of the devil. But honour abroad is followed by danger at home, and in order to rule others a man is first their servant, and prostrates himself in obedience that he may be rewarded with honours, and the higher he aspires the lower he bends with feigned humility; whence he adds, If thou will fall down and worship me.
