These strophes are a copy of the very last strophes from the prophecy of the Popes, attributed to Malachai.
It is always fun to consider prophecies before the facts, after the facts and also during the facts.
A couple of things stand out.
Every pope item that is mentioned with a cryptic sentence, ends with a dot.
Using the framework of dots as ends that demark popes, it is in the full sequence that Pope Benedict XVI would be Gloria oliuæ.
But then after Benedict, something strange happens.
The last two phrases definitively start with a capital letter and close with a dot, and are also remarkably paraphrased as two recognizable paragraphs.
S.R.E normally means Sacrae Romana Ecclesia. Note that the word Catholic did not exist yet. In this sense this phrase would be a phrase in itself.
In psecutione extrema Sacrae Romana Ecclesia sedebit.
In extreme persecution sits the Holy Roman Church.
This would mean a time of nothing. Sedevacantism maybe.
The current times I would argue, while it is clear that the seat occupier is not really making wise decisions, not acting like a pope. Destroying the church of Christ.
What I also see is a dot after the word psecutione(btw spelling error). It is like the writer wanted to finish the sentence right there, but then something made him add something extra. In my experience that is how prophecy works. Once you think you are ready is when divine intervention appears.
Some people also interpret this same phrase as a subsentence of the phrase that follows. In that case, they simply omit the dot and the paraphrasing and the capitalizing and see both paragraphs as one sentence. In that case, the whole last phrase would mean.
In the final persecution of the Holy Roman Church, there will sit Peter the Roman, who will pasture his sheep in many tribulations, and when these things are finished, the city of seven hills will be destroyed, and the dreadful judge will judge his people. The End. In this setting with the dots, the capitalization and the paraphrasing, it is highly unlikely this is the case. Even so, this is the most cited interpretation, but it would mean that Francis would be Peter the Roman who fixes everything. Doubtfull.
Another consideration is that an acronym can mean anything.
imagine S.R.E could mean something like Sapiens Rege Emeritus.
In that case this phrase contains some extra information. It would mean:
In extreme persecution sits the wise retired king.
