(the Lamb occurs 34 times in 29 verses in 27 songs)
Return Oh holy Dove, return
(this meaning of Dove only occurs in two other songs)
"The Lamb" is Jesus Christ, e.g.
John 1:29 (KJV)
The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
Revelation 22:1 (KJV)
And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb.
"the Dove" is the Holy Spirit, e.g.
Matthew 3:16 (KJV)
And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him.
(It looks like the four references to Jesus' baptism in the four Gospels - Matthew, Mark, Luke, and John - are the only places where this association is made. It has been a very common subject for artists.)

Okay, this may seem a bit too basic -- if so I invite you to reflect on how many people now are growing up without even the most basic knowledge of Biblical stories, the stuff needed just to understand and appreciate great swathes of European/western culture. After 25 years of preaching I am still caught off balance by what people haven't been exposed to in any helpful way.
