O lux beata Trinitas,
Et principalis Unitas,
Iam sol recedit igneus,
Infunde lumen cordibus.

Te mane laudum carmine,
Te deprecamur vespere:
Te nostra supplex gloria to you,
Per cuncta laudet saecula.
O blessed light of Trinity,
and fundamental Unity,
as now the fiery sun departs,
instil your light within our hearts.

To you our morning song of praise,
to you our evening prayer we raise;
through supplication low
eternal praise and glory go.
