+    Amor Jesu dulcíssime,
+
+    Quando cor nostrum vísitas,
+
+    Pellis mentis calíginem,
+
+    Et nos reples dulcédine.
+
+
+    Quam felix est quem sátias!
+
+    Consors patérnæ déxteræ,
+
+    Tu vere lumen pátriæ,
+
+    Quod omnem sensum súperat.
+
+
+    Splendor patérnæ glóriæ,
+
+    Incomprehénsa bónitas,
+
+    Amóris tui cópiam
+
+    Da nobis per præséntiam.
+
+
+    Glória tibi Dómine,
+
+    Qui apparuísti hódie,
+
+    Cum Patre et Sancto Spíritu,
+
+    In sempitérna sǽcula. Amen.

+    Light of the anxious heart,
+
+    Jesus, thou dost appear,
+
+    To bid the gloom of guilt depart,
+
+    And shed thy sweetness here.
+
+
+    Joyous is he, with whom,
+
+    God's Word, thou dost abide;
+
+    Sweet light of our eternal home,
+
+    To fleshly sense denied.
+
+
+    Brightness of God above!
+
+    Unfathomable grace!
+
+    Thy presence be a fount of love
+
+    Within thy chosen place.
+
+
+    To thee, whom children see,
+
+    The Father ever blest,
+
+    The Holy Spirit, One and Three,
+
+    Be endless praise addrest. Amen.
