Whether one ought, by humility, to subject oneself to all men?

Objections

Objection 1 : It would seem that one ought not, by humility, to subject oneself to all men. For, as stated above (Article [2], ad 3), humility consists chiefly in man's subjection to God. Now one ought not to offer to a man that which is due to God, as is the case with all acts of religious worship. Therefore, by humility, one ought not to subject oneself to man.
Objection 2 : Further, Augustine says (De Nat. et Gratia xxxiv): "Humility should take the part of truth, not of falsehood." Now some men are of the highest rank, who cannot, without falsehood, subject themselves to their inferiors. Therefore one ought not, by humility, to subject oneself to all men.
Objection 3 : Further no one ought to do that which conduces to the detriment of another's spiritual welfare. But if a man subject himself to another by humility, this is detrimental to the person to whom he subjects himself; for the latter might wax proud, or despise the other. Hence Augustine says in his Rule (Ep. ccxi): "Lest through excessive humility the superior lose his authority." Therefore a man ought not, by humility, to subject himself to all.
