Preparatory Prayer - For Each Novena to a Holy Helper

 (say 1 Our Father, 1 Hail Mary and 1 Glory Be each day of the Novena) 

ALMIGHTY and eternal God! With lively faith and reverently worshiping Thy Divine Majesty, I prostrate myself before Thee and invoke with filial trust Thy supreme bounty and mercy. Illumine the darkness of my intellect with a ray of Thy Heavenly light and inflame my heart with the fire of Thy Divine love, that I may contemplate the great virtues and merits of the Saint in whose honor I make this novena, and following his example imitate, like him, the life of Thy Divine Son. Moreover, I beseech Thee to grant graciously, through the merits and intercession of this powerful Helper, the petition which through him I humbly place before Thee, devoutly saying, "Thy will be done on earth as it is in Heaven." Vouchsafe graciously to hear it, if it redounds to Thy greater glory and to the salvation of my soul. Amen.

Through Christ our Lord. Amen.

Invocation of St. Barbara 

INTREPID Virgin and Martyr, St. Barbara, through thy intercession come to my aid in all needs of my soul. Obtain for me the grace to be preserved from a sudden and unprovided death; assist me in my agony, when my senses are benumbed and I am in the throes of death. Then, O powerful patroness of the dying, come to my aid! Repel from me all the assaults and temptations of the evil one, and obtain for me the grace to receive before death the holy Sacraments, that I breathe forth my soul confirmed in faith, hope, and charity, and be worthy to enter eternal glory. Amen.

St. Barbara, at my last end Obtain for me the Sacrament; Assist one in that direst need When I my God and Judge must meet: That robed in sanctifying grace My soul may stand before His face. Amen. 

Prayer - My Lord and God! I offer up to Thee my petition in union with the bitter passion and death of Jesus Christ, Thy Son, together with the merits of His immaculate and blessed Mother, Mary ever virgin, and of all the Saints, particularly with those of the holy Helper in whose honor I make this novena. Look down upon me, merciful Lord! Grant me Thy grace and Thy love, and graciously hear my prayer. Amen.
