Mystici Corporis Christi §47
Mystici Corporis Christi: On the Mystical Body of Christ
47 It is the will of Jesus Christ that the whole body of the Church, no less than the individual members, should resemble Him. And we see this realized when, following in the footsteps of her Founder, the Church teaches, governs, and offers the divine Sacrifice. When she embraces the evangelical counsels she reflects the Redeemer's poverty, obedience and virginal purity. Adorned with institutes of many different kinds as with so many precious jewels, she represents Christ deep in prayer on the mountain, or preaching to the people, or healing the sick and wounded and bringing sinners back to the path of virtue - in a word, doing good to all. What wonder then, if, while on this earth she, like Christ, suffer persecutions, insults and sorrows.
