Among the many popular saints in the Catholic Church is the 3rd-century martyr St. Agatha.
She experienced excruciating torture for her Christian faith and was martyred around 251.
Here is a prayer by an anonymous author to St. Agatha for health of mind, body and soul.
O Heavenly Father,
who raised Agatha to the dignity of sainthood,
we implore Your Divine Majesty by her intercession
to give us health of mind, body and soul.
Free us from all those things which hold us bound to this earth,
and let our spirit, like hers, rise to your heavenly courts.
Through Jesus Christ, your Son, our Lord,
who lives and reigns with you, forever. Amen.
