“Through the sacraments of Christian initiation, man receives the new life of
Christ.  Now we carry this life ‘in earthen vessels’, and it remains ‘hidden with
Christ in God’.  We are still in our ‘earthly tent’, subject to suffering,
illness, and death.  This new life as a child of God can be weakened and even
lost by sin.

healingThe Lord Jesus Christ, physician of our souls and bodies, who forgave the sins of the paralytic and restored him to bodily health, has willed that his Church continue, in the power of the Holy Spirit, his work of healing
and salvation, even among her own members.  This is the purpose of the two
sacraments of healing: the sacrament of Penance and the sacrament of Anointing
of the Sick.”    (CCC, 1420-21)
