Saint Joseph, I, your unworthy child, greet you. You are the faithful protector and intercessor of all who love and venerate you. You know that I have special confidence in you and that, after Jesus and Mary, I place all my hope of salvation in you, for you are especially powerful with God and will never abandon your faithful servants. Therefore I humbly invoke you and commend myself, with all who are dear to me and all that belong to me, to your intercession. I beg of you, by your love for Jesus and Mary, not to abandon me during life and to assist me at the hour of my death.
Glorious Saint Joseph, spouse of the Immaculate Virgin, obtain for me a pure, humble, charitable mind, and perfect resignation to the divine Will. Be my guide, my father, and my model through life that I may merit to die as you did in the arms of Jesus and Mary.
Loving Saint Joseph, faithful follower of Jesus Christ, I raise my heart to you to implore your powerful intercession in obtaining from the Divine Heart of Jesus all the graces necessary for my spiritual and temporal welfare, particularly the grace of a happy death, and the special grace I now implore:
(Mention your request). Guardian of the Word Incarnate, I feel confident that your prayers in my behalf will be graciously heard before the throne of God. Amen.
Saint Joseph, I thank God for your privilege of being able to die in the arms of Jesus and Mary. As a token of your own gratitude to God, obtain for me the grace of a happy death. Help me to spend each day in preparation for death. May I, too, accept death in the spirit of resignation to God's Holy Will, and die, as you did, in the arms of Jesus, strengthened by Holy Viaticum, and in the arms of Mary, with her rosary in my hand and her name on my lips!

Prayer to St. Joseph to Obtain a Special Favor
O blessed Saint Joseph, tenderhearted father, faithful guardian of Jesus, chaste spouse of the Mother of God, we pray and beseech thee to offer to God the Father His divine Son, bathed in blood on the Cross for sinners, and through the thrice-holy Name of Jesus, obtain for us from the Eternal Father the favor we implore.
(Name your request.)
Appease the Divine anger so justly inflamed by our crimes, beg of Jesus mercy for thy children. Amid the splendors of eternity, forget not the sorrows of those who suffer, those who pray, those who weep; stay the Almighty arm which smites us, that by thy prayers and those of thy most holy spouse, the Heart of Jesus may be moved to pity and to pardon. Amen. St. Joseph, pray for us.
In the Biblical sense how can Joseph be called Mary’s husband if they did not become one flesh?
