Prayers at a weddin g  reception are quite appropriate, especially when the couple has a relationship with the Lord. These prayers may include a blessing over the food, a father’s or mother’s prayer for their children and even blessings offered by the best man and maid of honor. Here are 6 great samples from which to choose.
A Prayer Of Blessing & A Charge From the Bible:
Dear Heavenly Father, “for this cause I bow my knees unto the Father of our Lord Jesus Christ, Of whom the whole family in heaven and earth is named, That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit  in the inner man; That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love, May be able to comprehend with all saints what is the breadth, and length, and depth, and height; And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God. Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us, Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.” (From Paul’s letter to the Ephesians 3:14-21)
A Prayer in a Song
A very popular thing at weddings is to sing a blessing. I have known of it to be done in person or in a video. The song  “The Prayer” is a great one that can be offered by anyone; I have even known the bride and the groom to do it as a duet at the reception. Here is a video of “The Prayer” with lyrics, sung by Chloë Agnew of the Celtic Women singing group.
A Prayer for the Food
The prayer for the food is usually offered by the minister who officiated the ceremony, however, it is also common for this prayer to be offered by the father of the bride.
“Lord, behold our family here assembled. We thank you for this place in which we dwell, for the love that unites us, for the peace accorded us this day, for the hope with which we expect the morrow, for the health, the work, the food, and the bright skies that make our lives delightful; for our friends in all parts of the earth. We pray your blessings on the food that you have provided for us and thank you for all who have prepared it for our nourishment. Thank you in Jesus’ name, Amen.” (includes “The Wedding Prayer” by Robert Louis Stevenson)
Traditional Hebrew Blessings
A Hebrew Wedding Blessing
This is called the Seudah. It is asked two times at the wedding; once at the ceremony  and then another time at the festival meal (Seudat Mitvah). Traditionally, the blessings are recited by seven different people that have been preselected by the bride and groom. This is also known as the Grace after meals (Birkat HaMazon). This blessing is performed while the groom and bride and all of the guest share a glass of wine. At the end of the blessing it is traditional that the groom breaks his glass with his foot, which is in remembrance of the temple that no longer exists in Jerusalem. At the end of the blessing everyone shouts “Mozol Tov”, indicating congratulations to the bride and groom. 
Blessing 1: Blessed art the LORD our God, King of the universe, Fashioner of man.
Blessing 2: Blessed art the LORD our God, King of the universe, Fashioner of man.
Blessing 3: Blessed art the LORD our God, King of the universe, who formed the man in His image, in the image of the semblance of His likeness, and prepared for him from Himself a building for eternity. Blessed art Thou LORD, who fashioned the man.
Blessing 4: May the barren one exult and jubilantly rejoice through the regathering of her children amidst her in gladness. Blessed art Thou LORD, who makes Zion rejoice with her children.
Blessing 5: Gladden the beloved companions as you made glad your creation in the garden of Eden from days of old. Blessed art Thou, LORD, who gladdens groom and bride.
Blessing 6: Blessed art Thou LORD our God, King of the universe, who created joy and gladness, groom and bride, rejoicing, glad song, pleasure, delight, love, brotherhood, peace and companionship. Soon, LORD, our God, let there be heard in the cities of Judah and in the streets of Jerusalem the sound of joy and the sound of gladness, the voice of the groom and the voice of the bride, the sound of jubilation of grooms from their canopies and of youths from their feasts of song. Blessed art Thou, LORD, who gladdens the groom with the bride.
Blessing 7: Blessed art Thou LORD our God, King of the universe, Creator of the fruit of the vine.

Traditional Irish BlessingMay the road rise to meet you,
May the wind be always at your back.
May the sun shine warm upon your face,
The rains fall soft upon your fields.
And until we meet again,
May God hold you in the palm of his hand. May God be with you and bless you;
May you see your children’s children.
May you be poor in misfortune,
Rich in blessings,
May you know nothing but happiness
From this day forward. May the road rise to meet you
May the wind be always at your back
May the warm rays of sun fall upon your home
And may the hand of a friend always be near. May green be the grass you walk on,
May blue be the skies above you,
May pure be the joys that surround you,
May true be the hearts that love you.
