# Trinity Sunday's own Matins hymn ("Summæ Deus cleméntiæ") — shares its
# opening stanza with the plain ferial Saturday hymn
# (matins-hymn-ferial-saturday.yml's "Summæ Deus cleméntiæ, Mundíque
# Factor máchinæ..."), but diverges completely from its second stanza
# onward and is shorter overall (2 body stanzas + its own doxology,
# not 4 + the shared weekday doxology) — a genuinely different hymn, not
# a mislabeled duplicate. Live-verified against Divinum Officium
# (Monastic Tridentinum 1617), Matins live query, 2026-05-31 (Trinity
# Sunday itself). Self-contained — its own final stanza is a fixed,
# unique doxology, not the shared weekday one.

    Summæ Deus cleméntiæ,

    Mundíque Factor máchinæ,

    Unus potentiáliter,

    Trinúsque personáliter.


    Da déxteram surgéntibus,

    Exsúrgat ut mens sóbria,

    Flagrans et in laudem Dei,

    Grates repéndet débitas.


    Glória Patri Dómino,

    Glória Unigénito,

    Una cum Sancto Spíritu,

    In sempitérna sǽcula. Amen.

    O God, by whose command is swayed

    This ordered world which thou hast made;

    Parent of heavenly clemency,

    In nature One, in persons Three;


    Assist us while our minds we raise,

    Inflamed with thy immortal praise;

    That with our sober thoughts, we may

    Forever our thanksgiving pay.


    May age by age thy wonders tell,

    Eternal praise thy works reveal,

    And sing with the celestial host

    The Father, Son, and Holy Ghost. Amen.
