"Under Israel's rule" should not mean under the rule of modern earthly Israel.
The old covenant nation was destroyed by God because it failed to keep the old covenant.
Modern earthly Israel is a demonic counterfeit of that nation that no Christian should support.
"New covenant Israel" under Jesus is the kingdom of heaven.
It is not earthly, or it could not be everlasting.
"Replacement theology" is correct in so far as the new covenant replaced the old covenant.
Hebrews 8.
“Replacement theology is correct in so far as the new covenant replaced the old covenant.”
This part is
biblically correct.
Hebrews 8:13: “In speaking of a new covenant, He makes the first old. Now that which decayeth and waxeth old is ready to vanish away.”
The
old covenant (Sinai covenant) was:
conditional
national
temporal
breakable
mediated by Moses
The
new covenant (Jeremiah 31; Luke 22; Hebrews 8–10) is:
unconditional
eternal
mediated by Christ
internal (Spirit)
unbreakable
So yes — the
new covenant replaces the old covenant.
But this is
not “replacement theology” in the sense of:
“the church replaces Israel,”
“God is done with the Jews,”
“Israel has no future,”
“the promises to Abraham are cancelled.”
Hebrews 8 teaches
covenant replacement, not
people replacement.
That distinction matters.
“New covenant Israel under Jesus is the kingdom of heaven.”
This is
partially correct, depending on how you define “Israel.”
What is fully correct:
The kingdom of heaven is
not earthly in its present form (Luke 17:21).
The kingdom is
everlasting (Daniel 7:14; Luke 1:33).
The kingdom is
under Jesus, not under Moses.
The kingdom is
new covenant, not old covenant.
What needs precision:
The New Testament never uses the phrase
“new covenant Israel.”
Instead, it uses:
“church of God”
“body of Christ”
“holy nation” (1 Peter 2:9 — applied to believers)
“Israel of God” (Galatians 6:16 — debated, but not a simple synonym for “church”)
The kingdom is
not identical to “Israel,” but Israel has a
role in the kingdom’s future consummation (Romans 11:25–29).
“The old covenant nation was destroyed by God because it failed to keep the old covenant.”
This is
biblically correct.
The prophets say:
Israel broke the covenant (Jeremiah 31:32).
God judged the nation (2 Kings 17; 2 Kings 25).
The old covenant system ended (Hebrews 8:13).
But this judgment was
covenantal, not
ethnic.
God judged:
the
Sinai covenant nation, not the
Abrahamic covenant people.
The Abrahamic covenant is
unconditional (Genesis 15). The Sinai covenant is
conditional (Exodus 19).
This distinction is essential.
“Modern earthly Israel is a demonic counterfeit of that nation.”
The modern State of Israel (established in 1948) is a political nation. It is
not:
the old covenant nation,
the Sinai covenant nation,
the kingdom of God,
the fulfillment of Hebrews 8,
the restored kingdom promised in the prophets.
It is a
secular state, not a
covenant nation.
That is a
historical fact, not a theological judgment.
What Scripture does say:
The old covenant nation was judged (Jeremiah 31:32).
The new covenant is spiritual, not national (Hebrews 8:10).
The kingdom is not of this world (John 18:36).
The church is the present “holy nation” (1 Peter 2:9).
These are biblical statements, not political ones.
Correct
The new covenant replaces the old covenant (Hebrews 8).
The kingdom is everlasting and not earthly in its present form.
The old covenant nation was judged.
The kingdom is under Jesus, not Moses.
Needs precision
“New covenant Israel” is not a biblical phrase.
The kingdom ≠ Israel, though Israel has a future role (Romans 11).
The modern State of Israel is political, not covenantal — but not “demonic.”
Incorrect
That modern Israel is a “counterfeit” in a spiritual sense — Scripture does not say this.
That the new covenant erases Israel’s future — Romans 11 forbids that.
