1. Come, Ye Thankful People, Come. This hymn by Henry Alford is found in many hymnals, including Cantus Christi. Yet, the last stanza radically contradicts the theological perspective of the historic faith and of the editors of this hymnal. It is a witness to how we tend to bounce along unthinkingly through metrical hymns, which is something we would not do when chanting a text. The fourth stanza says:
Even so, Lord, quickly come. Bring thy final harvest home.
Gather thou thy people in, Free from sorrow, free from sin,
There, forever purified, In thy garner to abide.
Come, with all thine angels, come; Raise the glorious harvest home.
Now, as we’ve had occasion to say before, the Biblical expectation is that Jesus will successfully disciple all the nations of the earth, making all into theocracies under His rule, before any final apostasy and His return to judge the living and the dead. The “quick coming” in the book of Revelation has to do with the events of AD 70 and the destruction of Jerusalem and of the Oikumene. Asking Jesus to come quickly and end history is very wrong. It is asking Him to fail, asking Him not to evangelize the heathen. The fact is, though, that the first three stanzas of this hymn are excellent, for they only state that Jesus will someday return to judge. We should keep this hymn, but omit the last stanza.
2. Lo! He comes, with Clouds Descending. This is a second-coming hymn, and like many Arminian hymns, this by Charles Wesley, the assumption is that Jesus will return to the earth to reign. This is completely false. According to 1 Corinthians 15:24, when He returns, having destroyed all enemies, He gives the Kingdom to the Father. According to the catholic faith, Jesus is presently seated at the right hand of the Father, ruling as King of kings and Lord of lords. Thus, any hymn that teaches us that Jesus will return to reign is communicating false teaching.
The end of stanza 1, “God appears on earth reign,” can be changed to “Christ the Lord forever reigns.”
The final stanza is more of a mess: “Saviour, take the power and glory, Claim the kingdom for thine own. O come quickly, O come quickly, O come quickly! Alleluia! Come, Lord, come.” Well, no. That’s all very bad. Change to this:
Lord, Thou hast taken all the pow’r and glory,
Thine the Kingdom e’er shall be!
Alleluia, Alleluia, Alleluia!
Thou dost reign, and we with Thee!
By the way, the best tune for this is Helmsley by Arne.

“Asking Jesus to come quickly and end history is very wrong. It is asking Him to fail, asking Him not to evangelize the heathen. ”
If you believe that Jesus will not come until he has succeeded in evangelizing the nations (which I do), then asking Him to come quickly is equivalent to asking Him to use the Church to bring about His victory quickly, thereby enabling Him to come.
Asking Jesus to come quickly and end history is *not* very wrong. It is, in fact, something that all good Christians, including (and especially) all good postmillennials should ask.
I have also wondered about Christ reigning on earth, and how it fits with God being all in all. Christ’s throne endures for ever, so his reign is not limited. I think that Paul is saying that God the Father’s reign will become visible to us, with Christ continuing to reign under him as Viceroy.
