I look at it in the light of the Churchs increased focus on ‘eschatology’ ie. the study of last things. Pope Francis himself lives his life as though he may die tomorrow and with urgency to promote the values of the end times. Contemporary Jewish scholars and theologians are also in the mode of focusing on ‘the days of the Messiah’.
According to Jewish tradition, the messianic era will be one of global harmony, a future era of universal peace and brotherhood on earth, and one conducive to the furtherment of the knowledge of the Creator. In this context, the earliest meaning of the word “messianic” is derived from notion of Yemot HaMashiach meaning “the days of the Messiah”, meaning “related to the Jewish Messiah”. The Jewish Messiah ushering in an era of universal peace is given expression in two scriptural passages from the Book of Isaiah:
They shall beat their swords into plowshares and their spears into pruning hooks; nation will not lift sword against nation and they will no longer study warfare. (Isaiah 2:4)
The wolf will live with the lamb, the leopard will lie down with the goat, the calf and the lion and the yearling together; and a little child will lead them. The cow will feed with the bear, their young will lie down together, and the lion will eat straw like the ox. The infant will play near the hole of the cobra, and the young child put his hand into the viper’s nest. They will neither harm nor destroy on my entire holy mountain, for the earth will be full of the knowledge of the Lord as the waters cover the sea. (Isaiah 11:6-9)
According to the Book of Jeremiah, Moab and Biblical Elam which were exiled during the Babylonian Exile, will be brought back from their captivity in the end of days.[25]
In the Book of Jeremiah, it is referenced by Jeremiah, who, speaking in the days of Josiah (Jer. 3:16), prophesied a future time, possibly the end of days, when the Ark will no longer be talked about or be made again:
“And it shall be that when you multiply and become fruitful in the land, in those days - the word of the LORD - they will no longer say, ‘The Ark of the Covenant of the LORD’ and it will not come to mind; they will not mention it, and will not recall it, and it will not be used any more.” - Jeremiah 3:16
Rashi comments on this verse that “The entire people will be so imbued with the spirit of sanctity that God’s Presence will rest upon them collectively, as if the congregation itself was the Ark of the Covenant.”[26]

I feel very comfortable with the Popes guidance since to be able to recognise the coming Christ, we need to accept the unity prophesied as the environment of the end times.
For perspective, I think of the difficulty the Pharisees had with recognising the Messiah before them. So limited by their loyalty to temporal aspects of tradition were they that they just couldn’t except this character who bore no resemblence to the Messiah they had created in their own minds.
It makes sense that all people that seek God will have the capacity to recognise the coming Christ and His unifying spirit. Wanting to cling to division and separateness in that time may be the downfall of many with a rigid concept of Christ.
