O God, who from the family of your servant David raised up Joseph to be the guardian of your incarnate Son and the spouse of his virgin mother: Give us grace to imitate his uprightness of life and his obedience to your commands; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever.
