For instance, these two quotes from Caryll Houselander (1901-1954), aka The Divine Eccentric. Caryll was a convert who endured a nightmarish childhood and ever after had an especially deep and tender bond with traumatized children.
"I am sure, as never before, that the Russian idea of Christ, humble, suffering, and crowned with thorns is the only true one; that it is impossible to be a Christian unless the humility of poverty of Christ is taken literally and all that tends towards power, grandeur, success and so on, is avoided and despised."
