There are different interpretations among people who study the writings on Divine Will given to the Church through the servant of God Luisa Piccaretta. All those who follow Luisa believe that she was the first to receive the grace of living in the Divine Will on earth by faith since Our Lady's Assumption two thousand years ago. Some believe that after Luisa received the grace of Living or dwelling in Divine Will many other saints have also lived in Divine Will such as St Therese, St Pope John II, St Maximilian Kolbe, St Elizabeth of the Trinity etc. These other saints and mystics are often referred to as exemplars of Divine Will. St Hannibale di Francia who was one of Luisa's confessors is considered the first priest to have lived in the grace of Divine Will on earth through following the teachings and writings of Luisa Piccarreta. Others believe that only Luisa has lived in Divine Will and that the next one to live in Divine Will on earth will be a future Pope who will then bring the priests into the Divine Will and then the priests will lead the people into the grace of living in the Divine Will.
This idea that the Pope will lead the rest of us is found in the "Three Appeals" where it speaks of the Pope as the first sun of the Divine Will that will lead us to era of the one shepherd and one flock. Of course "first" could mean in importance rather than in precedence in time. However many years ago I came to realise that there seemed to be three levels within the grace of living in the Divine Will in the eternal mode. I later found evidence for these levels beyond the mystical marriage on earth in the life of Luisa Piccarreta. I listed these levels as the first level of Living in Divine Will as Divine Indwelling or Mystical Incarnation, the second as Mystical Crucifixion and the third level as that of the Mystical Resurrection.
Luisa received the mystical marriage on earth in the Divine mode on October 16, 1888 and on September 7 1889 when she was 24 she received the grace of living in the Divine Will in the eternal mode at the first level of the Divine Indwelling or Mystical Incarnation. It is possible that Pope Leo XIII (or possibly Pius X) was the first Pope to live in the Divine Will at this level. Luisa entered the second level of Mystical Crucifixion sometime after 1889 and before 1900. The first Pope to live at this level was most probably St. Pope John Paul II (but it may have been Pius XII). Luisa entered the third and highest level of living in Divine Will in eternal mode of Mystical Resurrection on November 16 1900 at the age of 35.We now await the Pope who will live at this level who will be the first sun of the Divine Volition who will lead the priests into living in Divine Will at this highest level. This will usher in the era of the Kingdom of the Divine Will reigning on earth as in Heaven within history.
Just as Catholics are free to have different theological ideas on many aspect of Christian faith so those who are part of the Divine Will movement have different perspectives and understandings. All of this is healthy if they are all ready to accept any corrections by the Church and the Pope and don't teach about the grace of the Divine Will as a novelty that is in discontinuity with Scripture and Tradition but as a newness in continuity according to the development of doctrine in the Catholic Church, set and rooted within the whole of the Catholic teaching found in Scripture and Tradition as safe guarded and proposed by the Papal Magisterium.
The writings of Luisa point to a mystical or Divine Will level of interpreting Ezekiel 37 by referring to the era of one shepherd in one flock as also being the era of the Kingdom of the Divine Will reigning on earth. This chapter can refer to the level of living in Divine Will as the level of the Mystical Resurrection which is also referred to in Romans 11. This mystery of the Divine Will is connected with the reunion of Judaism and Christianity into one fold or flock under David the Prince (the Great Monarch of Catholic prophecy who is also the messenger (angel) of Apoc.10 according to many older Catholic writers) and the one Shepherd or Pope who reunites all in the one fold. The walls of division will be broken down until the rise of the final antichrist Gog at the end of the era of Peace.
The stick of Joseph in the hand of Ephraim alludes to Joseph as representing the Pope and Church and Ephraim as the Russian and Slavic peoples (a nation and a company of nations) as well as the other tribes of the House of Israel. Luisa's writings mention the important roles of Russia, France, Germany, Italy, China and England who will one day be devout Catholic nations after a time of purification by chastisement. They will be reunited with the stick of Judah which are the Jews and the so-called Anglo-Saxon-Gaelic or English-speaking peoples of the British Isles including Ireland and their descendants in America, Australia, New Zealand and Canada of the Davidic House of Nathan descended from Judah.
"Now there will be an exchange: if Jerusalem gave to Rome the life of religion and therefore of Redemption, Rome will give to Jerusalem the Kingdom of the Divine Will. This is so true, that just as I chose a Virgin from the little town of Nazareth for the Redemption, so I have chosen another virgin [Luisa Piccarreta] in a little town [Corato]belonging to Rome, to whom the mission of the Kingdom of the Divine Fiat has been entrusted. And since this must be known in Rome just as my coming upon earth was known in Jerusalem, Rome will have the great honour of requiting Jerusalem for the great gift received from her, which is the Redemption, by making known to her the Kindgdom of my Will. Then will Jerusalem repent of her ingratitude, and will embrace the life of the religion which she gave to Rome; and, grateful, she will receive from Rome the life and the great gift of the Kingdom of my Divine Will. And not only Jerusalem, but all the other nations will receive the great gift of the Kingdom of My Fiat, the first criers of It, Its gospel - all full of peace, of happiness and of the restoration of the creation of man. And not only will my manifestations bring sanctity, joys, peace and happiness, but the whole of Creation, competing with them, will unleash from each created thing each of the happinesses it contains, and will pour them upon creatures...".
Note: The tribe of Ephraim is mainly found among the Russian and Slavic descendants of r1a z283 ydna. Eastern Manasseh is R1a z93+ z2124+ ydna are the original Turks (the great nation) or Xiongnu. Southern Manasseh is R1a z93+ L657+ ydna who were known as the Mancy or Manxi originally of South East Asia and Northern ancient Australia. The Turks and the other Muslim Manassehites will also one day be converted to Catholic through Our Lady of Fatima. Some Ashkenazi Jews of Khazar ancestry also belong to R1a z93. Western Manasseh is R1a L664 along with other Western R1a that hasn't been given a haplogroup yet. Some believe there are also many Manassehites found in the USA due to Jewish and German immigration.
