Prayer to St. John the Baptist from My Pope
Oh God, you gave St. Elizabeth, in her old age, the gift of a son, St. John the Baptist, who would prepare the way for Jesus to begin His ministry here on earth.
Lord, Fill Your people with the joy of possessing graces like those of Saint John the Baptist, and direct the minds of all us in the way of salvation and peace. St. John was martyred for truth and justice, so may we Dear God, energetically profess our Faith in You, and help us to lead others to Your Way, Your Truth, and Your Eternal Life. Amen.
