I remember addressing him on his conclusion, that the Fatima secrete had to do with Apocalypse 12. So I asked; if this be true, then why aren’t you preaching the Second Coming of Christ? His answer; yeah yeah yeah.

Presbyter Nicholas Gruner (Left) Remained Attached And even Deepened his Attachment to the Newchurch Of the Marxist/Modernist Newpope Francis-Bergoglio (Right) And His Predecessor Newpopes.
Unfortunately, Presbyter Gruner Bought Into The Exaggerated and unCatholic Version of Fatima Which Proclaimed the Heresy That “Fatima” Is Equal in Authority to Sacred Scripture
Dear TRADITIO Fathers:
After the death of presbyter Nicholas Gruner in 2015, his “Fatima Crusade” has been carried on by others. I have always been uncertain about the status of Gruner and his crusade. I notice that the organization is now including the names of post-Vatican II Newsaints in its litanies. Was presbyter Gruner and those that succeed him traditionally Catholic or not?
The TRADITIO Fathers Reply.
The late presbyter Gruner remained a member of the Newchurch of the New Order to the end. He even fought to remain in it when Newchurch wanted to suspend him. Contrast Gruner’s attitude to that of the courageous Archbishop Lefebvre, who, when purportedly “excommunicated” from Newchurch in 1988, essentially said, Fine; Newchurch is not Catholic anyway, and I want no part of it.
Moreover, it seemed that presbyter Gruner became cozier and cozier with the New Order heresy at the end, whereas at the beginning he railed against the phony “New Mess.” That topic was hardly mentioned in the last editions of his Fatima Crusader. Thus, his ministry was tainted with the Newchurch heresy. Although he seems at first to have had a relatively sincere attachment to Fatima, he and his Fatima Crusade later became cozier and cozier with a brood of Newchurch cardinals, bishops, and presbyters, who became embroiled in Newchurch’s Great Sex & Embezzlement Holocaust.
“Fatima” is an issue fraught with gross misconceptions and even heresies. As a private devotion, Fatima is one thing, and that is how it was regarded at first, as well as being subordinate to established Marian devotions such as those to Our Lady of Lourdes and Our Lady of Guadalupe. But after the heretical Vatican II Anti-council (1962-1965), Fatima took on a life of its own, obsessed with unCatholic notions about “end times” and “secrets.” Shortly after the Anti-council, long-standing devotions to Our Lord, such as the Sacred Heart, the Precious Blood, the Holy Name, Corpus Christi, and Christ the King, were being displaced by an exaggerated “New Age” exaltation of Fatima above the dogmatic teaching of the Church. Moreover, at least by implication, Fatima extremists were making the Blessed Virgin Mary into a goddess — and that is the outright heresy of idolatry: elevating a creature or object above God Himself, a grave sin against the First Commandment of God.
Unfortunately, presbyter Gruner also bought into this exaggerated and unCatholic version of Fatima and wrote that “Fatima” was equal in authority to Sacred Scripture. Such a belief is outright heresy, as no apparition after the Apostolic period has any part in the Public Revelation of the Church, which dogmatically consists only of Sacred Scripture (“the Bible”) and Sacred Tradition (teaching handed down from Christ’s Apostles).
