The divided Israelite Kingdom in Rome was made up of the Orthodox Catholic Christendom in the Western Roman Empire and the Eastern Roman Empire. The Church in the unified Roman Empire was the United Israelite Kingdom, the Church in the Eastern Roman Empire was the Northern Kingdom of Israel, and the Church in the Western Roman Empire was the Kingdom of Judah.
The United Israelite Kingdom was united around Christianity, which was retained in the Western Roman Empire after the fall of the Eastern Roman Empire. The Eastern Roman Empire was converted to Islam to portray how the Northern Kingdom of Israel drifted away from the worship in Jerusalem. Jerusalem here was Rome which retained Christianity after the Fall of Constantinople.
Orthodox Catholic Christianity was effectively overwhelmed by Islam in the Eastern Roman Empire to demonstrate the end of the United Israelite Kingdom and the beginning of the divided Israelite Kingdom.
The Orthodox Catholic Christendom was divided into two through the prophecy of the prophet Ahijah to Jeroboam,
“As Jeroboam was traveling from Jerusalem, the prophet Ahijah, from Shiloh, met him alone on the road in the open country. Ahijah took off the new robe he was wearing, tore it into twelve pieces, and said to Jeroboam, “Take ten pieces for yourself, because the LORD, the God of Israel, says to you, ‘I am going to take the kingdom away from Solomon, and I will give you ten tribes” (1 Kings 11:29-31)
Tore it into twelve pieces: the twelve pieces were the twelve tribes of Israel constituting the Orthodox Catholic Christendom in the Roman Empire
Take ten pieces: the Northern Kingdom of Israel, which was the Eastern Roman Empire, was given ten tribes of Israel out of the twelve tribes of Israel.
King Solomon is the epitome of Holy Wisdom; therefore the Orthodox Catholic Christendom, at its height of cultivation of Holy Wisdom, was the Kingdom of Solomon. Hence the separation of the Roman Empire into east and west was the division of the United Israelite Kingdom into ISRAEL AND JUDAH.
Since ten tribes were given to the Eastern Roman Empire, the Muslims, who took over the Eastern Roman Empire, were the ten tribes of the Northern kingdom of Israel.
There were five patriarchates at the height of the hierarchy of the Orthodox Catholic Christendom. Four out of the five patriarchates sank with the fall of the Orthodox Catholic Christendom, and they were substituted by Islam. Every patriarchate retaining Orthodoxy went down with the Orthodox Catholic Christendom at the end of the Thousand Years. The Fall of Constantinople was the height and the end of Holy Wisdom scheduled for the era of the Orthodox Catholic Church.
Holy Wisdom was however retained by the Holy See of Rome like the Temple of God remained in Jerusalem after the United Israelite Kingdom was divided. This means that the Holy See of Rome was the one tribe – the tribe of Judah – retained by Solomon.
“Solomon will keep one tribe, for the sake of my servant David and for the sake of Jerusalem, the city I have chosen to be my own from the whole land of Israel” (1 Kings 11:32)
The Holy See of Rome was the next level of Christianity after the era of the Orthodox Catholic Church. The Holy See was transformed to the institution of the Roman Catholic Church.
