This is not true. You can look through a lot of Papal documents and books on the style of writing of the Papal Chancery and you will see that these phrases are adopted in many documents. (There is one book online
here)
I cannot understand why Fr. Kranmer would consider the “the wrath of Almighty God, etc.” an unusual clause. “Nulli ergo hominem” and “Si quis autem” is extremely common in all manner of Papal documents.
Papal documents typically speak in such an extravagant style. When Pius XII declared the BVM the Principal Patroness of my (ecclesiastical) region, the letter contained such impressive statements as it ‘was always valid and binding, both now and n the future’ , ‘anything attempted against it, by whatsoever authority, is null and void’. It hardly means that if my bishop, in consultation with the clergy and CDW in Rome, decides to change the principal patroness, a future Pope cannot do it or mandate it be done.
**As an example, see the Bull Quod a Nobis on the breviary.
In it St. Pius V declares:
Omni itaque alio usu quibuslibet, ut dictum est, interdicto, hoc Nostrum Breviarium, ac precandi psallendique formulam in omnibus universi orbis Ecclesiis, Monasteriis, Ordinibus, et locis etiam exemptis, in quibus Officium ex more et ritu dictae Romanae Ecclesiae dici debet, aut consuevit, salva praedicta institutione, vel consuetudine praedictos ducentos annos superante, praecipimus observari:
Statuentes Breviarium ipsum nullo umquam tempore vel totum, vel ex parte mutandum, vel ei aliquid addendum, vel omnino detrahendum esse;
ac quoscumque, qui Horas Canonicas ex more et ritu ipsius Romanae Ecclesiae, iure vel consuetudine dicere vel psallere debent, propositis poenis per Canonicas sanctiones constitutis in eos, qui divinum Officium quotidie non dixerint,
ad dicendum et psallendum posthac in perpetuum Horas ipsas diurnas et nocturnas, ex huius Romani Breviarii praescripto et ratione omnino teneri: neminemque ex iis, quibus hoc dicendi psallendique munus necessario impositum est, nisi hac sola formula satisfacere posse………
…Nulli ergo omnino hominum liceat hanc paginaem Nostrae ablationis, abolitionis, permissionis, revocationis, iussionis, praecepti, statuti, indulti, mandati, decreti, relaxationis, cohortationis, prohibitionis, innodationis, et voluntatis infringere, vel ei ausu temerario contraire. Si quis autem hoc attentare praesumpserit, indignationem omnipotentis Dei, ac beatorum Petri et Pauli Apostolorum eius se noverit incursurum.
You can see the parallels yourself with Quo Primum. The last paragraph, Nulli ergo, etc. is virtually identical with that of Quod a Nobis- this was a standard formula.
Despite this decree, Popes altered the breviary and St. Pius X completely changed the order of reciting the psalms - essentially annuling Quod a Nobis by saying that anyone who adhered to the psalter of the previous breviary (i.e. St. Pius V’s) did not fulfil the obligation to recite the Canonical hours. **
Fr. Kranmer argues that “perpetua valitura constitutione” is “precise and unequivocal meaning: namely, that the document cannot ever be revoked or modified”. But there are a multitude of other Papal bulls and minor documents where the expression “perpetua valitura constitutione” has been used but they have later been overturned. Anyone can go through (e.g.) a compendium of such documents and see it.Take the Sixtine Vulgate. Pope Sixtus’ constitution on the Vulgate uses the same words to command that his version be used “provera, legitima, authentica, et indubitata” yet, as you know, it only lasted until Clement VIII.
