Jesus said himself

Matthew 16:27-28 - “The Son of Man will come in the glory of His Father with His angels, and then He will reward each according to his works. Assuredly, I say to you, there are some standing here who shall not taste death till they see the Son of Man coming in His kingdom.”

All the apostles and NT believers were “eagerly waiting" (Philippians 3:20) on the Parousia in their times. We must be able to understand the biblical time statements and audience relevancy. 

What we see in the fabricated phantom duplication's of history of the millennium on earth was only a shadow of the eternal kingdom. We have to remember the heavenly things are often shadows of the earthly things and it tells us that in the Bible in many different places. 

For example We know that Jesus said that he is the fulfilment of Sabbath rest. We also know that Man is not made for Sabbath but sabbath is made for men (Mark 2:27). That eternal Sabbath is found in the risen Lord Jesus Christ. Which is why we are supposed to dwell “in Christ”, after God raised the man (Jesus) from the dead Jesus was placed in his glorified kingdom in his glorified body as the life-giving spirit (1 Corinthians 15), and that was the start of the true eternal kingdom which was consummated (manifest in fullness) at the fall of Jerusalem. 

This eternal kingdom has no end and is without sight, and is where we as believers/saints are supposed to dwell. Verses supporting no end - Luke 1:33, Revelation 11:15, Psalm 89:29, Daniel 7:14 ect.). Verses supporting spiritual/non observable - Luke 17:20.

The Jesuit sect operated as a sort of early proto-intelligence agency for the Catholic Church. How did they set the template by which other secular intelligence agencies evolve?

A code of instructions alleged to be addressed by Acquaviva, the fifth general of the Society, to its various superiors, and laying down the methods to be adopted for the increase of its power and influence. According to them, every means is to be employed of acquiring wealth for the order, by enticing promising young men to enter it and endow it with their estates; rich widows are to be cajoled and dissuaded from remarriage; every means is to be used for the advancement of Jesuits to bishoprics or other ecclesiastical dignities and to discredit the members of other orders, while the world is to be persuaded that the Societies animated by the purest and least interested motives: the reputation of those who quit it is to be assailed and traduced in every way.
