The relapse theory often goes hand-in-hand with replacement theologies, and these ideologies often utilize Hebrews 8 as a text that teaches that the ‘old’ is done. But as we have seen, the author’s appeal to Jeremiah 31 does not need to serve an antinomian or supersessionist argument. Instead, the author’s interpretation of the quotation presents God restoring his relationship with his people and instituting another covenant that pertains to the heavenly realm that the people will experience fully in the future. - Madison N.
