Hymns and Confession/Doctrine and Practice

I found out about a hymn by Wilhelm Loehe which is in the LSB (Lutheran Service Book). However, due to our synod publishing house's greediness (I'm speaking facetiously), only folks who have a copy of the Hymnal may read it. They could at least give us samples of new additions to our synodical hymnary on the web. It would probably incline people to want a bound copy. I, possibly wrongly, assume Wilhelm Loehe wouldn't have wanted his hymn in praise of Jesus Christ in the sacrament of the altar to become a bought and traded commodity. There is no other English Translation I've found, but I snooped this small portion from the google monster:


The sacrament God gives us
Binds us in unity,
Joins earth with heav’n beyond us
Time with eternity. (LSB 639, st. 3)

-Wilhelm Loehe's Wide Open Stands the Gates Adorned with Pearl.


...and this is INCREDIBLY amazing (amazingly stupid) CPH has also copywrited part of St. Thomas Aquinas's Thee We Adore, O hidden Savior, Thee (How is that possible?)

Here's a pasted example from hymnary.org:

LSB 640: Thee We Adore, O Hidden Savior

1 Thee we adore, O hidden Savior, Thee,

Who in Thy Sacrament art please to be;

Both flesh and spirit in thy presence fail,
Yet here Thy presence we devoutly hail.

(Sts. 2 and 3 copyrighted)

4 Fountain of goodness, Jesus, Lord and God:
Cleanse us, unclean, with Thy most cleansing blood;
Increase our faith and love, that we may know
The hope and peace which from thy presence flow.

5 O Christ, whom now beneath a veil we see,
May what we thirst for soon our portion be:
To gaze on Thee unveiled and see Thy face,
The vision of Thy glory, and Thy grace.

Amen.

-Thomas Aquinas/CPH's(lol) Thee We Adore, Hidden Savior thee

Anyways, I was thinking about how our hymnals are a type of confession of faith. Hymns, ideally, teach from the word of God; therefore, I wonder if a synodically approved hymn could be considered a confession of it's faith. I'm thinking of the historical example of the LBW (Lutheran Book of Worship). The Missouri Synod began it's creation yet didn't sanction the finished product. It's use was approved by the ELCA though, and I believe most ELCA liturgical congregations still use it.

Is the way we worship the way we believe?
