I don't know anything about their teaching.
What I have spoken of is written in His Word.
In Ezekiel, in the chapters about the millennium and after He tells us where we will be...on what side of the river. In a vision an angel showed the future to Ezekiel. They came from the altar to the outer gate of the city, the holy city Jerusalem. Healing waters, waters to teach, are flowing from the altar of the Lamb.....
Ezekiel 47:3-5 And when the man that had the line in his hand went forth eastward, he measured a thousand cubits, and he brought me through the waters; the waters were
to the ancles. Again he measured a thousand, and brought me through the waters; the waters were
to the knees. Again he measured a thousand, and brought me through; the waters were
to the loins. Afterward he measured a thousand; and it was a river that
I could not pass over: for the waters were risen, waters to swim in,
a river that could not be passed over.
The same river is mentioned in the chapter about eternity.....
Revelation 22:1-3 And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb. In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations. And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and His servants shall serve Him;
47:6-7 And he said unto me, "Son of man, hast thou seen this?" Then he brought me, and caused me to return to the brink of the river. Now when I had returned, behold, at the bank of the river were
very many trees on the one side and on the other.
Our Saviour, the Word, is The Tree of Life. His elect, those He abides in, are His trees that teach His Word, His healing word. Notice that there is a division and that division cannot be crossed. Those on one side will not be of the holy city but...they ARE NOT destroyed. They will be healed.
47:8-9 Then said he unto me, "These waters issue out toward the east country, and go down into the desert, and go into the sea: which being brought forth into the sea, the
waters shall be healed. And it shall come to pass, that
every thing that liveth, which moveth, whithersoever the rivers shall come, shall live; and there shall be a very
great multitude of fish, because these waters shall come thither; for
they shall be healed; and every thing shall live whither the river cometh.
Waters are symbolic of not only the river of life but of people, the people that need healing....
Revelation 17:15 And he saith unto me, The waters which thou sawest, where the harlot sitteth, are peoples, and multitudes, and nations, and tongues.
47:10-11 And it shall come to pass, that
the fishers shall stand upon it from En-gedi even unto En-eglaim; they shall be a place to spread forth nets;
their fish shall be according to their kinds, as the fish of the great sea, exceeding many. But the miry places thereof and the marishes thereof
shall not be healed; they shall be given to salt.
The fishers of course are those, like Peter, that fish for men, for the souls of men...the fish being "their kinds." The different nations? But, of those not all "shall be healed." They are past redemption.
47:12 And by the river upon the bank therof, on this side and on that side, shall grow
all trees for meat, whose leaf shall not fade, neither shall the fruit therof be consumed: it shall bring forth new fruit according to his months,
because their waters they issued out of the sanctuary: and the fruit thereof shall be
for meat, and the leaf therof
for medicine."
For meat to learn of His Word.
For medicine to heal souls. Again, the trees are His elect that are filled with His Spirit...filled with the
"waters of the sanctuary."
