19 Nor is that all; for in the Holy Eucharist the faithful are nourished and strengthened at the same banquet and by a divine, ineffable bond are united with each other and with the Divine Head of the whole Body. Finally, like a devoted mother, the Church is at the bedside of those who are sick unto death; and if it be not always God's will that by the holy anointing she restore health to the mortal body, nevertheless she administers spiritual medicine to the wounded soul and sends new citizens to heaven - to be her new advocates - who will enjoy forever the happiness of God.
