"The Church's One Foundation"

"The Church's One Foundation" was a hymn in a church service I watched a couple months ago.  Later, I was thinking about the hymn and noticed a couple features.

The first two lines of the second verse are "Elect from ev'ry nation, / Yet one o'er all the earth," sung to these phrases from the tune "Aurelia":

The phrase "o'er all the earth" is sung to all different pitches (B A G F#), musically giving a sense of that breadth.

The fifth (and last) verse ends with the lines "That we, like saints before us, / May see You face to face," sung to these phrases:

The two "face"s are both sung to the same pitch (D), so even musically, they're on the same level, eye-to-eye, as it were.

"O Father, All Creating"

One of the hymns I sang in church a few months ago is "O Father, All Creating."  I noticed a small connection between the tune ("Aurelia") and the text in the third verse.  The first two lines of the third verse are "O Spirit of the Father, / Breathe on them from above."  (The hymn is in the marriage section of the hymnal; the "them" in the line refers to a newly wedded couple.)  The second half of the second line descends:

To some degree, this musically represents the Spirit's "Breath[ing] on them from above."
