I. Its Foundations in the Economy of Salvation

From The Catechism of the Catholic Church

1502
The man of the Old Testament lives his sickness in the presence of God. It is
before God that he laments his illness, and it is of God, Master of life and
death, that he implores healing.⁹⁸ Illness becomes a way to conversion;
God’s forgiveness initiates the healing.⁹⁹ It is the experience of
Israel that illness is mysteriously linked to sin and evil, and that
faithfulness to God according to his law restores life: “For I am the
Lord, your healer.”¹⁰⁰ The prophet intuits that suffering can also
have a redemptive meaning for the sins of others.¹⁰¹ Finally Isaiah
announces that God will usher in a time for Zion when he will pardon every
offense and heal every illness.¹⁰²
