>>Judeo-Christian is an oxymoron as Judeo rejected Christ and they do to this day
No, it’s an accurate term given the relationship between the Old and New Testaments.
The Old Testament articulates the Covenant of the Law with Israel. The OT also contains prophecy fulfilled by Jesus, and the OT is referred to by Jesus numerous time.
The New Testament articulates the New Covenant within the repentant and forgiven Body of Christ - which is His Church.
There’s also the matter of Jesus lineage being delivered through the children of Israel.
Considering that the ‘new covenant’ is defined by Paul & the Prophets as the one YHWH (the LORD) makes with house of Israel (Ephraim) and the house of Judah, and since that has not happened yet, then what is this ‘new covenant’ with the ‘church’ you speak of?
