Does anyone know the hymns in the movie the miracle 1959?

the miracle is a movie made in 1959 starring carroll baker and roger moore. the scene where roger moore's character ''Michael'' has been captured and taken to a prison camp. After some time he escapes and returns to the convent to take Teresa ''carroll baker'' with him to England to marry her. He's too late, the Mother Superior informs him, "Teresa is now the Bride of Christ," meaning that she has taken her final vows and is now a fully-fledged nun. Michael pushes past her only to find "Teresa" in full habit (actually the Virgin Mary impersonating her), singing in a procession. now what's that beautiful hymn her and the nun's were singing? i really really have to know
