That shares a sentiment with antiSemitism, to claim that because something is from Judaism, its current state of apostasy renders all of its teachings illegitimate. Jesus, however, said the opposite.
Matt 23.Then Jesus said to the crowds and to his disciples: 2 “The teachers of the law and the Pharisees sit in Moses’ seat. 3 So you must be careful to do everything they tell you. But do not do what they do, for they do not practice what they preach.
So you reject the Prophets' presentation of what I call "the Jewish Hope" simply because Judaism taught it? No wonder you're Amil--Amil dismissed all hope that God's promise to Abraham, concerning Israel, would finally be fulfilled, resulting in Israel's ultimate restoration as a nation. What Amil basically did was exchange the "Jewish Hope" for the Hope of a newly-defined "Israel," the International Church.
Acts 1.6 Then they gathered around him and asked him, “Lord, are you at this time going to restore the kingdom to Israel?”
7 He said to them: “It is not for you to know the times or dates the Father has set by his own authority.
The ironic thing is: in keeping with the early Amillennialists, many of the early Chiliasts emphasized the New Testament heavenly spiritual hope rather than an earthly carnal one, as most contemporary Premillennialists promote. They spiritualized the fulfillment of Israel's hope, relating it to the Church, the Promised Land being Christ, and (in doing so) expose the faulty Premil literalist obsession.
Chiliast Methodius (Bishop of Olympus, Asia Minor) denounces the materialistic approach of the apostate Jews (which sadly many Premillennialists advocate today):
[T]he Jews, fluttering about the bare letter of Scripture, like drones about the leaves of herbs, but not about flowers and fruits as the bee, fully believe that these words and ordinances were spoken concerning such a tabernacle as they erect; as if God delighted in those trivial adornments which they, preparing, fabricate from trees, not perceiving the wealth of good things to come; whereas these things, being like air and phantom shadows, foretell the resurrection and the putting up of our tabernacle that had fallen upon the earth, which at length, in the seventh thousand of years, resuming again immortal, we shall celebrate the great feast of true tabernacles in the new and indissoluble creation, the fruits of the earth having been gathered in, and men no longer begetting and begotten, but God resting from the works of creation (Banquet of the Ten Virgins, Discourse 9:1).
Methodius concludes, showing the feast of tabernacles to be a type of an incorruptible future millennial age:
Wherefore let it shame the Jews that they do not perceive the deep things of the Scriptures, thinking that nothing else than outward things are contained in the law and the prophets; for they, intent upon things earthly, have in greater esteem the riches of the world than the wealth which is of the soul (Banquet of the Ten Virgins, Discourse 9:1).
Tertullian wrote in Against Marcion Book III (Chapter 24):
As for the restoration of Judæa, however, which even the Jews themselves, induced by the names of places and countries, hope for just as it is described, it would be tedious to state at length how the figurative interpretation is spiritually applicable to Christ and His church, and to the character and fruits thereof … At present, too, it would be superfluous for this reason, that our inquiry relates to what is promised in heaven, not on earth. But we do confess our inquiry relates to what is promised in heaven, not on earth. But we do confess that a kingdom is promised to us upon the earth, although before heaven, only in another state of existence; inasmuch as it will be after the resurrection for a thousand years in the divinely-built city of Jerusalem, 'let down from heaven,' which the apostle also calls 'our mother from above;' and, while declaring that our citizenship, is in heaven, he predicates of it that it is really a city in heaven … We say that this city has been provided by God for receiving the saints on their resurrection, and refreshing them with the abundance of all really spiritual blessings, as a recompense for those which in the world we have either despised or lost; since it is both just and God-worthy that His servants should have their joy in the place where they have also suffered affliction for His name’s sake.
Tertullian (160 – 220 AD) said in Against Marcion, Book IV, Chapter 38:
You see how pertinent it was to the case in point. Because the question concerned the next world, and He was going to declare that no one marries there, He opens the way by laying down the principles that here, where there is death, there is also marriage. But they whom God shall account worthy of the possession of that world and the resurrection from the dead, neither marry nor are given in marriage; forasmuch as they cannot die any more, since they become equal to the angels, being made the children of God and of the resurrection.
Tertullian wrote in On the Resurrection of the Flesh (Chapter 26):
In Isaiah, “‘Ye shall eat the good of the land’, the expression means the blessings which await the flesh when in the kingdom of God it shall be renewed, and made like the angels, and waiting to obtain the things ‘which neither eye hath seen, nor ear heard, and which have not entered into the heart of man’ … You will reckon, (I suppose) onions and truffles among earth's bounties, since the Lord declares that ‘man shall not live on bread alone!’ In this way the Jews lose heavenly blessings, by confining their hopes to earthly ones, being ignorant of the promise of heavenly bread, and of the oil of God’s unction, and the wine of the Spirit, and of that water of life which has its vigour from the vine of Christ. On exactly the same principle, they consider the special soil of Judæa to be that very holy land, which ought rather to be interpreted of the Lord’s flesh, which, in all those who put on Christ, is thenceforward the holy land; holy indeed by the indwelling of the Holy Ghost, truly flowing with milk and honey by the sweetness of His assurance, truly Judæan by reason of the friendship of God.
Even Barnabas (who you wrongly claim was Premil) teaches The Epistle of Barnabas (Chapter 6):
[T]he prophet proclaimed, “Enter ye into the land flowing with milk and honey, and have dominion over it.” … We, then, are they whom He has led into the good land. What, then, mean milk and honey? This, that as the infant is kept alive first by honey, and then by milk, so also we, being quickened and kept alive by the faith of the promise and by the word, shall live ruling over the earth.
Barnabas spiritualises the Old Testament land promises in a manner that would cause modern premillennialists to go cross-eyed. This is a classic Amillennial approach to the fulfilment of Old Testament prophesies in a New Testament context. He also applies the promises made to natural Israel in the Old Testament to the New Testament church today.
J. Lebreton aptly remarks, “not indeed to the deep thought of the Church, but, at least, to the danger which Judaism constituted for it, and the Church’s reaction to the danger.”
Barnabas continues in Chapter XVI:
Let us inquire, then, if there still is a temple of God. There is—where He himself declared He would make and finish it. For it is written, “And it shall come to pass, when the week is completed, the temple of God shall be built in glory in the name of the Lord.” I find, therefore, that a temple does exist. Learn, then, how it shall be built in the name of the Lord. Before we believed in God, the habitation of our heart was corrupt and weak, as being indeed like a temple made with hands. For it was full of idolatry, and was a habitation of demons, through our doing such things as were opposed to [the will of] God. But it shall be built, observe ye, in the name of the Lord, in order that the temple of the Lord may be built in glory. How? Learn [as follows]. Having received the forgiveness of sins, and placed our trust in the name of the Lord, we have become new creatures, formed again from the beginning. Wherefore in our habitation God truly dwells in us. How? His word of faith; His calling of promise; the wisdom of the statutes; the commands of the doctrine; He himself prophesying in us; He himself dwelling in us … This is the spiritual temple built for the Lord.
This means that at an extremely early date, even perhaps overlapping with the writings of the Apostle John, there are those in the church who have replaced Israel entirely with the Church in terms of future blessings. As Diprose notes, ―Barnabas shows little respect for Old Testament institutions. For example, in chapter XVI, 7 a temple made with hands is likened to a habitation of demons, full of idolatry. The writing as a whole, manifests the latent presupposition that the Church, the true heir of the promises, occupies the place that Israel had always been unworthy of occupying. Obviously, to these kinds of Christians there can be no chiliastic hopes involving a restored national Israel, temple, and Jerusalem.
