Through Christ dying on the cross, the humanity which he bore whole and entire in his own person renounces itself and dies. But the mystery is deeper still. He who bore all men in himself was deserted by all. The universal man died alone…. This is the mystery of solitude and the mystery of severance, the only efficacious sign of gathering together and of unity: the sacred blade piercing indeed so deep as to separate soul from spirit [Heb. 4:12], but only that universal life might enter.
