[quote=Matt16_18]My guess is that Instit., 27:18 refers to the Institutiones Ecclesiasticæ.Pope Benedict XIV
Great as a man, a scholar, an administrator, and a priest, Benedict’s claim to immortality rests principally on his admirable ecclesiastical writings. The most important of them, besides those already mentioned, are: “Institutiones Ecclesiasticæ”, written in Italian, but translated into Latin by P. Ildephonsus a S. Carolo; it is a collection of 107 documents, principally pastoral letters, letters to bishops and others, independent treatises, instructions, etc., all of which are really scientific dissertations on subjects connected with church law or the care of souls; the classical work “De Synodo Dioecesanâ”, published after his elevation to the papacy, an adaptation to diocesan administration of the general ecclesiastical law; this book is called by Schulte, because of its influence, one of the most important, if not the most important, modern work in canon law; “Casus Conscientiæ de mandato Prosp. Lambertini Archiep. Bonon propositi et resoluti”, valuable for the lawyer as well as the confessor; “Bullarum Benedicti XIV”, which contains the legislation of his pontificate, many of its documents being scientific treatises.

I bet you’re right, and I bet we won’t be finding copies of that collection online and in English
In this case, however, I’m willing to give the benefit of the doubt to Pope Pius X that he wasn’t taking things completely out of context. Even if he were, those documents don’t sound like they’d reach anything near the level of infallility, and many of them likely aren’t even technically “by Papal authority”, but by “Prospero Lorenzo Lambertini, who also happens to be the Pope”, not unlike John Paul II’s numerous private and pastoral writings during his Pontificate.
Peace and God bless!
