The first line of the bull reads "Audita tremendi severitate judicii, quod super terram Jerusalem divina manus exercuit...", in English "On hearing with what severe and terrible judgement the land of Jerusalem has been smitten by the divine hand..." (the phrase "audita severitate" is a Latin grammatical construction known as ablative absolute).
Как и все папские буллы, Audita tremendi получила название по первым словам: ""Audita tremendi severitate judicii, quod super terram Jerusalem divina manus exercuit...", то есть ""Услышав о страшном и суровом суде, которым Божественная рука поразила землю Иерусалима"".
