You will have to elaborate on this more as to what you are saying for this scripture you have posted.. I will wait for the response to this one before I ask on the other ones..
The Escatological Church is the Church of the saints:
Rev 22:3-5
There shall no more be anything accursed, but the throne of God and of the Lamb shall be in it, and his servants shall worship him; they shall see his face, and his name shall be on their foreheads.
(this quote explain why I call the Echatological Church the
Church of saints)
That is not only a description of the future, but also of the present!
22:2
also, on either side of the river, the tree of life with its twelve kinds of fruit, yielding its fruit each month; and the leaves of the tree were for the healing of the nations
It is clear that the need of a
healing places the description in the present times, because only now there is the need of a healing.
Rev 22:1
Then he showed me the river of the water of life, bright as crystal, flowing from the throne of God and of the Lamb
Rev 22:2
through the middle of the street of the city; also, on either side of the river, the tree of life with its twelve kinds of fruit, yielding its fruit each month; and the leaves of the tree were for the healing of the nations.
And the
river of live flowing from the throne is surely the WORD of GOD (see Ez 47:1 - a Ortohodox would say the Liturgy, a Protestan would say the Bible, a Catholic would say the Word of God): and there we can find the Body of Christ.
And the trees on each side of the river are the belivers, by which, trasfigured by Christ, the healing power of Christ (Zec 13:1) arrives to all the the others (nations).
The Eschatological Church is already present, even if not completly.
That is in the same way the death as been already defeated by Christ, but we still bodly die. (1Cor 15:54
Death is swallowed up in victory)
We are allowed to unit ourself, even if only partially, to the Eschatological Church by the Incarnation-Death-Risen of Christ.
This event is painted in the Revelation by the opening of the seventh seal, opened by the Lamb (Rev 8:1).
PS: the Ecclesiology (doctrine of the Church) is much more developed in Catholic Church (that has it in common with the Orthodox Church, due to the fact that the Ecclesiology was already developed in the 3 century), while the standard Protestant Ecclesiology is more simplified, and it is usually focused on the Echatological Church (see ad instance the OSAS/predestination), while the Visible Church is sometime too much developed in the CC (see the importance of sacraments), and the Personal Church is sometime too much developed in the EO (see the importance of the monks)
PPSS: the more clear contact point with the Eshatological Church is when, in almost all denomination services, we say something like:
And so with all the choirs of angels in heaven we proclaim Your glory and join in their unending hymn of praise:
Holy, holy, holy Lord, God of power and might, heaven and earth are full of your glory.....
