Justin also describes the spiritual nature of the kingdom that is approaching as spiritual and heavenly:..
Justin did not look for an earthly temporary human kingdom on this earth when Christ comes, but a heavenly one...
Justin explains that those in Christ are spiritual Israel and the true offspring of Abraham, Isaac, Jacob and Judah. The new covenant is an ongoing arrangement from the cross and man’s only hope of salvation....
Jerusalem is here spiritualized and is shown to be the abode of the elect of God throughout the nations. Coming to Jerusalem is depicted as coming to “to the light of the Lord.” It is a picture of salvation.
The early Church fathers believed that old covenant national theocratic Israel is long-finished through the introduction of the new covenant – which is focused on all nations equally. In their estimation the Church is true Israel, spiritual Jews, the children of promise, Abraham’s seed. Race is no longer a benefit, simply grace. All nations can encounter Christ today and be spiritually circumcised. This is all classic Amillennial theology.
All Christians believe in the New Covenant, and believe that the Abrahamic Promises are fulfilled in people who follow that New Covenant, both Jew and non-Jew. You prove nothing in this! We agree that Israel and the nations are fulfilled not in the Old Covenant of Law, which applied only to Israel, but rather, in the New Covenant of Christ.
This has nothing to do with whether God's promises are still to be literally fulfilled in the Jewish race and in the nation of Israel. It has nothing to do with your sense of Jerusalem being a purely "spiritual city" in heaven!
You completely bypass the fact that Justin saw Jerusalem as an *earthly reality.* By spiritualizing it as a heavenly reality he did not render Jerusalem *non-earthly!* On the contrary, he views Jerusalem as still earthly, and yet enhanced by its new Christian definition.
Justin saw, as Paul did, a joining of non-Jewish nationals to the spiritualized Israeli nation. Israel did not lose its literal value, as such, for Justin. It just excluded those who failed to live by God's laws, and were thus, cut off, as even the Law indicated. He was reducing the definition of "Israel" to include only Christians in its ultimate form.
Furthermore, "Spiritual Israel" becomes, for Justin, a "nation" of many nations not because it ceased to refer to a literal nationality or race, but because the promises made to Abraham concerned a single people consisting of Abraham's faith, and yet expressed in both literal Israel and many nations. So "Spiritual Israel" did not, for Justin, cease to consist of Natural Israel along with Many Nations. When they have Christian Faith they all become part of "Spiritual Israel" for Justin. But Israel does not stop being literal Israel, assuming we're speaking of Jews with Christian faith.
At this point let me say that Justin's definition of "Spiritual Israel" leans in the direction of Replacement Theology, which I disagree with. However, he does not go so far as to discount Jewish inclusion in this promised Salvation, nor does he go as far as some Amills who may wish to believe the end of the Old Covenant ended literal Israel's hope in the Abrahamic Covenant.
We know that at Jesus' 1st Coming, most of Israel rejected Christianity. So Israel is being viewed by both Paul and Justin in her ideal form, as her call to eventually become a godly nation once again. Justin merely expanded his notion of the nation "Israel" to include Gentile Christians along with Jewish Christians, as the Abrahamic Promise indicated. The point is, "Israel" didn't stop referring to literal physical Israel for Justin, nor did it exclude Jewish People. It was just reduced to Christian Jews, and it was expanded to include other nationalities.
You may very well agree with this? But do you believe that the Abrahamic Promises were being literally fulfilled in Natural Israel, when they will turn to Christianity? No. But Justin apparently felt that a Jewish remnant does maintain hope in such a future reality, though it is less clear that this will result in anything more than Jewish inclusion, as a racial group, in the international Church.
When we read the blessings and curses of the Law, we note that it implied that Israel will at times, as a nation, obey and be blessed, while at other times disobey and be cursed. This has nothing to do with obtaining Salvation under the Law.
Many get sidetracked by the thought that this has to do with individual Salvation--it does not! It has to do with God promising to bless *nations* that obey His laws.
So even though Israel experiences disobedience in the current NT era, it does not imply that individual Jews do not retain these promises of Christian obedience. Neither does it imply that Israel, as a nation, cannot return again to obedience and to blessing. However, if individual Salvation remains active for the individual Jew that embraces Christianity, then God's promises to Israel is still being literally fulfilled for literal Jews!
My main point is that Justin, despite these "spiritual" and "heavenly" references to earthly realities, did not mean by this that they are fulfilled as such as non-earthly entities. I believe it is quite the contrary, since he believed in a literal thousand year Kingdom in earthly Jerusalem. All of your references to "heavenly" or "spiritual" Jerusalem does not successfully refute this!
Nor does Justin's reference to a "spiritualized Israel" mean that God's promises to Abraham were not literally being fulfilled *on earth* through a literal remnant of Israel and through the joining of non-Jewish nationals. On the contrary, his "spiritualized" sense of "Israel" retained its earthly grounding--these things were merely enhanced by their identification with Christianity and the New Covenant.
That is, the literal meaning of Jerusalem and Israel was not being changed substantially with respect to their earthly grounding. Rather, they were simply being reduced to things that fit God's spiritual qualifications as Christian realities. Literal Jews and other nations were to be literally fulfilled in this "Spiritual Israel" in the thousand year Kingdom, though in a sense they already exist. Clearly, for Justin, they are not yet completely fulfilled, and will require a future development. This is *not* Amillennialism!
And if Justin referred to literal Jews, and to literal Israel, despite its "spiritual qualifications and the inclusion of Gentiles with it," then the fulfillment of such in a literal earthly Jerusalem makes more sense.
It is "heavenly" in the sense it is not yet here. It is "spiritual" in the sense it must be Christian. And it is on earth in the sense it must literally fulfill God's promises to Abraham. There must be a literal Jewish People, a literal Israel, and this literal Israel must have joined with it many other Christian nations. Justin's use of the term "Spiritual Israel" to include less than a full Israeli nation and the inclusion of many other nations does not in the least remove his sense of their literal fulfillment on earth. He simply loses faith that these ethnicities can become successful national entities, since Israel had failed at that.
If so, all this must take place *on earth,* because it has not yet been fulfilled in the eyes of Justin. That's why he promises a future Millennial Kingdom, replete with these earthly realities. His "spiritualized" version of "Israel," therefore, is hardly Amillennial, as you propose. On the contrary, the Abrahamic Promises retain their original values. It only introduces the necessity of Christian fulfillment.
Incidentally, you did not provide any quotations from the Church Fathers indicating their view of the Millennium is "goat infested," as you indicated? Why?
