I have a match (wedding song) with what you want. O Perfect Love by
The wells Cathedral Choir.

O Perfect Love, all human thought transcending,
Lowly we kneel in pray'r before Thy throne
That their's may be the love which knows no ending
Whom Thou forever more dost join in one.

O Perfect Life be Thou their full assurance
Of tender charity and steadfast love
Of patient hope and quiet brave endurance
With childlike trust that fears no pain or death.

Grant them that joy that brightens earthly sorrow
Grant them the peace which calms all earthly strife
And to life's day the glorious unknown morrow
That dawns upon eternal love and life.
