O Faithful servants of God and powerful protectors of man, Holy Helpers! Since Our Lord appointed you the heavenly advocates for our needs on earth, I confidently turn to you for help in my distress. Countless numbers praise you for aiding them with counsel in doubt, with consolation in anxiety, with health in illness, with safety in danger, with delivery from prison, and with help and assistance in all tribulations. Therefore I, too, have recourse to you, and implore you not to refuse me your aid.
Give thanks to God for me for all the graces He grants me during this novena. I ascribe them to your great merits and powerful intercession. I thank you all together, and each one in particular, for your interest in my favor, _______, before the throne of God. I commend myself to your continued protection, that I may one day be united with you in heaven, there to thank the Giver of all good things and to praise Him for all eternity.
Amen.
