Jam sol recedit - vespers hymn for Trinity Sunday

Day 36 of #100daysofchant

I love how this hymn for Trinity Sunday has 3 verses. Plus it's almost exactly the same as the regular Vespers hymn for Saturdays.

Jam sol recedit igneus:
Tu lux perennis Unitas,
Nostris, beata Trinitas,
Infunde lumen cordibus.

Te mane laudum carmine,
Te deprecamur vespere;
Digneria ut te supplices
Laudemus inter cœlites.

Patri, simulque Filio,
Tibique sancta Spiritus,
Sicut fuit, sit jugiter
Sæclum per omne Gloria.

As fades the glowing orb of day,
To Thee, great source of light, we pray;
Blest Three in One, to every heart
Thy beams of life and love impart.

At early down, at close of day,
To Thee our vows we humbly pay;
May we, mid joys that never end,
With Thy bright Saints in homage bend.

To God, the Father, and the Son,
And Holy Spirit, Three in One,
Be endless glory, as before
The world began, so evermore.
