{This blessing is not to be found in the latest edition of the Roman Ritual of 1952, for its composition is of later origin, and was approved by the Congregation of Sacred Rites on October 24, 1957 (see AAS 49 [1957] 1043-45).}

From the nearest church or from another place designated for the purpose the priest proceeds to the radio-station, chanting or reciting the Canticle of Zachary or the Canticle of the Three Youths. On arriving at the radio-station he intones the following antiphon and then says psalm 18:

P: Ant.: Through all the earth their voice resounds, * and to the ends of the world their message.

Psalm 18

P: The heavens declare the glory of God, * and the firmament proclaims His handiwork.

All: Day pours out the word to day, * and night to night imparts knowledge;

P: Not a word nor a discourse * whose voice is not heard;

All: Through all the earth their voice resounds, * and to the ends of the world, their message.

P: He has pitched a tent there for the sun, which comes forth like the groom from his bridal chamber * and, like a giant, joyfully runs its course.

All: At one end of the heavens it comes forth, and its course is to their other end; * nothing escapes its heat.

P: The law of the Lord is perfect, refreshing the soul; * the decree of the Lord is trustworthy, giving wisdom to the simple.

All: The precepts of the Lord are right, rejoicing the heart; * the command of the Lord is clear, enlightening the eye;

P: The fear of the Lord is pure, enduring forever; * the ordinances of the Lord are true, all of them just;

All: They are more precious than gold, than a heap of purest gold; * sweeter also than syrup or honey from the comb.

P: Though your servant is careful of them, * very diligent in keeping them.

All: Yet who can detect failings? * Cleanse me from my unknown faults!

P: From wanton sin especially, restrain your servant; * Let it not rule over me.

All: Then shall I be blameless and innocent * of serious sin.

P: Let the words of my mouth and the thought of my heart find favor * before you, O Lord, my rock and my Redeemer.

All: Glory be to the Father.

P: As it was in the beginning.

All: Ant.: Through all the earth their voice resounds, * and to the ends of the world their message.

Then the priest says:

P: Our help is in the name of the Lord.

All: Who made heaven and earth.

P: The Lord be with you.

All: May He also be with you.

Let us pray.

God, who ordered all things in creation in a marvelous way, determining even their measure, number, and weight; and who gave man a share in your knowledge, thus enabling him to detect and control the latent forces with which you endowed the things of the universe; be pleased, we pray, to bless + these instruments made for transmitting wavelengths of sound through the air, spreading out in all directions as instantaneously as lightning. Let them carry messages of aid in times of crises, of solace in times of distress, of advice in times of doubt, of light in times of darkness, and thus make known the glory of your name more widely throughout the world that all its peoples may be gathered into the fellowship of your love; through Christ our Lord.

All: Amen.
Let us pray.

Almighty everlasting God, who created the world by your Word, and decreed that all things be brought to a head in Him who was made flesh and who suffered for us; graciously grant that His Gospel may be preached to every creature on the wavelengths of sound, so that, aided by the prayers of the blessed Mary, Mother of God and ever a Virgin, and of St. Gabriel the Archangel, messenger of the heavenly mysteries, all peoples may be united in the body of Christ and be gladdened with the gift of His peace; through Christ our Lord.

All: Amen.

The radio-station is sprinkled with holy water. And after the blessing the “Te Deum” is sung or recited, together with its versicles and oration (see Renewal of the Marriage Vows).
