Prayer to My Guardian
My good angel, you come from heaven; God has sent you to take care of me. Shelter me in this present night; enfold me under your wings; lighten my heavy task; direct my steps. Do not leave me, be near me, defend me against the spirit of evil. But above all, come to my aid in the last struggle of my life. Deliver my soul so that with you it may praise, love and contemplate the goodness of God forever and ever. Amen.

Prayer to My Guardian Angel
Dear Angel, in His goodness God gave you to me
to guide, protect, and enlighten me,
and to bring me back to the right way when I go astray.
Encourage me when I am disheartened,
and instruct me when I err in judgment.
Help me to become more Christlike,
and so some day to be accepted
into the company of angels and saints in heaven.
Prayer to Our Guardian Angels
Heavenly Father, Your infinite love for us has chosen a blessed angel in heaven and appointed him our guide during this earthly pilgrimage. Accept our thanks for so great a blessing. Grant that we may experience the assistance of our holy protector in all our necessities. And you, holy, loving angel and guide, watch over us with all the tenderness of your angelic heart. Keep us always on the way that leads to heaven, and cease not to pray for us until we have attained our final destiny, eternal salvation. Then we shall love you for all eternity. We shall praise and glorify you unceasingly for all the good you have done for us while here on earth. Especially be a faithful and watchful protector of our children. Take our place, and supply what may be wanting to us through human frailty, short-sightedness, or sinful neglect. Lighten, O you perfect servants of God, our heavy task. Guide our children, that they may become like unto Jesus, may imitate Him faithfully, and persevere till they attain eternal life. Amen.
