St. Valentine is a Catholic saint who has become closely associated with the pursuit of love. One way we can honor him is by asking for his intercession with our prayers.
Here is a prayer to St. Valentine adapted from Dom Prosper Gueranger for any need you might have. He is a powerful intercessor, especially for those seeking love.
Pray then, O holy martyr St. Valentine, for the faithful,
who are so persevering in celebrating your memory.
The day of judgment will reveal to us all your glorious merits.
Intercede for us, especially in regards to [insert intention here],
that we may then be made your companions
at the right hand of the great Judge
and be united with you eternally in heaven.
Amen.
