Not only does it [the Sacrament of Penance] free us from our sins but it also challenges us to have the same kind of compassion and forgiveness for those who sin against us.  We are liberated to be forgivers.  We obtain new insight into the words of the Prayer of St. Francis: "It is in pardoning that we are pardoned."

Jesus entrusted the ministry of reconciliation to the Church.  The Sacrament of Penance is God's gift to us so that any sin committed after Baptism can be forgiven.  In confession we have the opportunity to repent and recover the grace of friendship with God. It is a holy moment in which we place ourselves in his presence and honestly acknowledge our sins, especially mortal sins.  With absolution, we are reconciled to God and the Church. The Sacrament helps us stay close to the truth that we cannot live without God. "In him we live and move and have our being" (Acts 17:28).

In the Church's Sacrament of Anointing of the Sick, through the ministry of the priest, it is Jesus who touches the sick to heal them from sin – and sometimes even from physical ailment. His cures were signs of the arrival of the Kingdom of God. The core message of his healing tells us of his plan to conquer sin and death by his dying and rising.

The Rite of Anointing tells us there is no need to wait until a person is at the point of death to receive the Sacrament. A careful judgment about the serious nature of the illness is sufficient.

When the Sacrament of Anointing of the Sick is given, the hoped-for effect is that, if it be God's will, the person be physically healed of illness. But even if there is no physical healing, the primary effect of the Sacrament is a spiritual healing by which the sick person receives the Holy Spirit's gift of peace and courage to deal with the difficulties that accompany serious illness or the frailty of old age.
