Gregory the Great — on 1Sam 1:13 (Commentary on 1 Kings, Book 1, Chapter 2)

“(Moral Exposition) She vows her son to Almighty God who seeks the joy of contemplation for the fruit of the mind, not for the favor of vanity. But carnal superiors are accustomed to resist vehemently those who rightly seek the desire of contemplation; for they think that those desiring a more secluded life act all the more foolishly, because they themselves are ignorant of the power of interior sweetness. If they sometimes rage against spiritual subjects with the voice of harsh rebuke, they must be calmed by the most humble reasoning. For if they unreasonably rise up against those acting rightly, the reverence due to the higher order requires that they be honored even when they exceed the measure of reason. Both of these—namely carnal prelates and spiritual subjects—Eli and Anna well represent; for when he sat before the doorposts of the Lord's temple and Anna prayed, Eli watched her mouth and called her drunk. But she, who patiently endured the insults, displayed humility of response with truthful reasoning. She declared herself his handmaid, speaking from much grief and sorrow, and not only calmed his angry spirit against her, but even turned him to prayer for obtaining the fruit of her desire.”
