How did this Jesuit priest devise his preterist views, what were they based on I wonder?
Then you have to ask the question, what did the Jesuits who promoted futurism base their views on also.
In 1585 a Spanish Jesuit called Francisco Ribera was commissioned by the Pope to write a commentary on the Book of Revelation, which was published as footnote in the Catholic Vulgate Version of the Bible.
He proposed that the first chapters of the Apocalypse/Revelation applied to ancient pagan Rome, and the rest to a literal 7 year period in the future. Immediately prior to the second coming. During that time, the Roman Catholic Church would have fallen away from the pope into apostasy, and the revealing of a single Antichrist would appear.
To do this he took the prophecy in the book of Daniel about the coming Messiah, commonly known as the 70 weeks, and took the confirmation of the New Covenant by Jesus Christs death on the cross, which caused all sacrifices and the oblations to cease, and said it was not about Christ, it was about a one man Anti-Christ who would appear during an end time great tribulation period.
Francisco Ribera's work was later furthered by an Italian Jesuit called Cardinal Robert Bellarmine. These works were published in 1591
Around 1791 a Chilean Jesuit priest called, Emmanuel Lacunza wrote a book called "The Coming of Messiah in Glory and Majesty", but he wrote it under the name of Rabbi Ben Ezra, passing himself of as a Jew who had converted to Christ. He was an advocate of Ribera's futurism, and thought that by hiding the fact that he was a Roman Catholic, and pretending to be a Jew, might give the book a better chance of acceptance amongst protestants, who were the target. The book was published in London, Spain, Mexico and Paris, between 1811 and 1826.
The Jesuit Ribera had brought forth the idea of a Rapture, stating that the church will be taken up to heaven 45 days before the end of the three and half years of Daniels 70th week. What is called the Gap theory. According to Ribera only those who partake of the Sacrament of the Eucharist (The Catholic Mass), will be raptured. The other Jesuit Emmanuel Lacunza also had a visible rapture of the church 45 days before the end of the three and half years.
