"Christ used the flesh and blood of Mary for his life on earth, the Word of love was uttered in her heartbeat. Christ used his own body to utter his love on earth; his perfectly real body, with bone and sinew and blood and tears; Christ uses our bodies to express his love on earth, our humanity. A Christian life is a sacramental life, it is not a life lived only in the mind, only by the soul... Our humanity is the substance of the sacramental life of Christ in us, like the wheat for the host, like the grape for the chalice."
