Agnus Dei spurred me on to have a closer look at the wealth of pieces in op 100 of Flor Peeters... I recently purchased 6-7 more of them used for a very attractive price ($5 each, I think). This is a festive setting of the Melita tune, used both for "My Hope is Built on Nothing Less" and "Eternal Father, Strong to Save" The Marcussen fits these pieces perfectly!
