No.
The following was sent to Robert Moynihan of "Inside the Vatican":
Dear Mr Moynihan,
I refer to an article “The Prophecy of St Nilus” which, I am told, appears in the October 2004 issue of “Inside the Vatican.”
Your website and some other Catholic websites allege that the author was the fifth century, St Nilus of Sinai, disciple of St John Chrysostom, died c. 430 AD. There is an entry in the c. 1912 Catholic Encyclopedia on this saint - but, there is no mention of any prophecies. In fact, in the ultimate paragraph it states that some of his alleged works were "spurious."
On the other hand, I have come across several Orthodox websites who quote the (almost) exact prophecy but attribute the prophecy to
1. St Nilus the Myrrhstreamer of Mt Athos (d. 1651?) a 17th century saint - http://www.oneearthasinheaven.com/nilus.html
2. Same as above at http://members.cox.net/orthodocheritage/St%20Nilus.htm and
3. An Australian website at http://home.it.net.au/~jgrapsas/pages/Prophecy.htm
Quoting St Nilus (14th Century). This entry has a few additions such as "...in three hypostases (Father, Son and Holy Spirit)" and "...and his servants."
Throughout history there have been many Sainst “Nilus”. However, I have been, thus far, unable to reconcile the entries - first as to which Saint, which Century and, more importantly, the original source document from which the "prophecy" allegedly originates. Obviously, someone is wrong. I suspect that the Orthodox is correct - but it also remains unsourced.
Can you please help me on this one by providing evidence that it is from a fifth Century original document?
Mr Moynihan replies that he "would check it out."
The facts are that the alleged prophecy refers to "after the yearv 1900, etc." The facts are that IF the (as we now know it) 4th century St Nilus WAS the author - he would NOT have used that expression - for the calendar (as we know it) was not thought of as "AD" until more than 100 years after the death of that ST Nilus; and not more fully acted upon until the time of St Bede in the 8th century.
The prophecy of St Nilus the Myrrhstreamer (of Mt Athos), 17th century - is regarded by the Orthodox as referring to the post 1917 subjection by the Communists!
I am afraid that "someone" appears to have invented the Prophecy to suit their agenda.
