This is true up to a point. There is such a thing in this dispensation as a racial Jew (1Cor.10:32)
When the Jews rejected both the Kingdom of God and Heaven as offered by Christ, the Kingdom was given to a new 'nation' the Church (Matt.22:23) and the Kingdom of Heaven (the literal, physical reign of Christ on earth) held in waiting until the new 'mystery'(Eph.3:3) body(Eph.1:28) could be completed. (Rom.11:25)
When Christ returns He will write the law on their hearts so they will be both spiritual and racial Jews (Heb.8:8, Jer.31:31)
I agree with everything else you said. The best work on the subject is George N.Peters, The Theocratic Kingdom (3Vol.)
