You know, it's really annoying when I sign in, and then the site signs me out after I submit a translation. Just saying.

Iffy Latin lyrics from an iffy source. Do not trust, unless they agree with what you've got.
The first part is a prayer about St. Benedict, and the last line seems to be a quote from him, or at least words put into his mouth....

Scande coeli limina,
anima sanctissima
per lampadum luces
Quos superi duces
Itineris obviam dant.
Sed quaeso quid nati
Qui tacti amore
Afflicti dolore
Hic orphani stant,
Cara o pignora, protegam vos
coeli ut patria societ nos.

Ascend the heavens' thresholds,
most holy soul,
by the lamps' light
Which those above give you as guides
Along your journey.
But I beg that sons
Who are stricken with love,
Afflicted with sorrow,
stand here orphans.
O precious pledge! "I will protect you
From Heaven, so that the Father's land may unite us."

Patria means fatherland and hence homeland, but it definitely means the Father's kingdom in this case. The sons are the Benedictines. "Children" would also be correct, I suppose, and there are female Benedictines too.

You are welcome.

And vetting is a very good idea, because my knowledge of Latin is full of unexpected holes....
