The Responsorial Psalm is a sometimes misunderstood part of the Catholic marriage ceremony. It is actually a part of the Liturgy of the Word- it is a scripture reading. Because it is a sung scripture reading, couples sometimes assume that they may request any song of their choosing to be sung as the Responsorial Psalm. In fact, the text for the Psalm must be taken from the Bible, usually from the book of Psalms.
There are several Psalm texts that are appropriate for weddings. You have hopefully been presented with a list of these as part of the planning process for your wedding Mass. However, I'd like to draw your attention to a Psalm setting created specifically to be used during wedding liturgies. The song is "Every Morning in Your Eyes (Psalm for Weddings)" composed by Rory Cooney.
I especially like the way this Psalm interweaves the symbolism of the love between a husband and wife and the love that God shares for each one of us. The first really has no meaning unless it is seen in the context of the second. Here is the text of the refrain:
"Every morning in your eyes, all my life,
I will bless God always ever near.
Near as you my friend.
Taste and see, touch and hear,
the faithful love of God"
It's a nice message presented in a poetic way. It is a rather lengthy refrain, so if we want the congregation to participate in singing, the text should be printed in your wedding program so that the people can refer to it.
The sheet music is available for purchase online, and you can also listen to a brief audio sample of the refrain. In addition, their are instrumental parts available for flute and string instruments. This would make for a lovely addition if you are hiring any additional instrumentalists. I would give this Psalm setting some strong consideration for your wedding Mass.
