Reddit mentions of Christ Jesus and the Jewish People Today: New Explorations of Theological Interrelationships

IMO, Hebrews presents the strongest case for replacement theology in the NT. So, for a Christian (like myself) who wants to avoid replacement theology, what can be done?

Some scholars, like Norbert Lohfink (The Covenant Never Revoked), will just say that the NT is not consistent on the question of the Old Covenant's irrevocablility; (replacement theology in Heb 8 vs. Rom 11:29 & Matt 5:17-20). Thus, we have to pick our lens, and Hebrews is only one of the possible lenses that we can prioritize.

Others take a stronger position and claim that Hebrews itself doesn't endorse a replacement theology. An example of this would be J. Svartvik's essay “Reading the Epistle to the Hebrews Without Presupposing Supersessionism” in Christ Jesus and the Jewish People Today. Svartvik's basic contention is that "Judaism" and "Christianity" aren't being compared in the epistle (such a neat and clean division would be anachronistic). Rather, what is passing away is the "present time" while the "future" has been inaugurated. That is, "this earthly age" is becoming obsolete, rather than Judaism. Our facile equation of "Old Covenant" with "Judaism" wasn't operative for the person writing Hebrews, according to Svartvik -- it's an equation which we import into the letter.

The summaries above are completely inadequate, so if the basic idea sparks an interest, there's a lot more detail and nuance in the essays themselves.
