In regards to Hymn 460, Stanza 3 ...
The "Amen. Alleluia" was intentionally left out of online Lutheran Service Builder as well as the Hymn Accompaniment Book. The vast majority of the time, Hymn 459 is sung with Hymn 460, back and forth. When done this way, the "Amen. Alleluia" would be followed immediately by more Alleluias, which doesn't make sense. Therefore, we opted to leave the "Amen. Alleluia" of Hymn 460, Stanza 3 out.
