St. Teresa de Avila Invoked against headaches and heart disease. Feast day October 15. Prayer: Dear wonderful Saint Teresa de Avila, model of fidelity to vows, you gladly carried a heavy cross following in the steps of Christ who chose to be crucified for us. You realized that God like a merciful Father chastises those whom he loves, which to worldlings seems silly indeed. Grant to (Name) relief from great pains if this is in line with God's plans. Amen.
