Anselm, Saint, Archbishop of Canterbury. [Letter to Matilda of Scotland, queen of the English, 1103] in Sancti Anselmi Cantuariensis Archiepiscopi Opera Omnia 4.207-08

[Letter from Anselm, archbishop of Canterbury, to Matilda of Scotland, queen of the English]
From exile, Anselm begs the queen to work for the peace of England's churches, to keep its orphans [monks] warm under her wings “like the chicken in the gospel,” in other words to be a Christ to them, filling the void created by the king’s actions.
