Not clamour, but love,
Not rumour but dedication,
Not violence but intelligence
Sings in the ear of God.

[Non clamor, sed amor,
non vox, sed votum,
non cordula, sed cor
cantat in aure Dei]

Thomas of Celano (c.1200 - c.1265) Italian friar, poet, hagiographer [Tommaso da Celano]
(Attributed)

A similar phrase -- "Not the voice but the deed, not the music of the heart but the heart, not noise but love sings in the ear of God" -- is attributed to Jordanus de Saxonia, an Augustinian hermit born in Quedlinburg in 1299.

Dies iræ! dies illa
Solvet sæclum in favilla
Teste David cum Sibylla!

Day of wrath! O day of mourning!
See fulfilled the prophets’ warning,
Heaven and earth in ashes burning!

Thomas of Celano (c.1200 - c.1265) Italian friar, poet, hagiographer [Tommaso da Celano]
“Dies Irae” (13th C.) [tr. Irons (1849)]
Alt. trans.:

"That day of wrath, that dreadful day,
shall heaven and earth in ashes lay,
as David and the Sybil say."

"Day of wrath, day that
will dissolve the world into burning coals,
as David bore witness with the Sibyl."
