Baptism Is A Central Covenantal Sign

  • Baptism is a commanded sign of church membership and the new covenant, tied directly to the gospel mandate to proclaim and baptize all nations.
  • Steve Wellum emphasizes baptism's theological weight: it signals what it means to be Christian and belongs within the whole covenantal storyline, not isolated texts.

Covenant Framework Drives The Baptism Debate

  • The baptism debate is fundamentally a covenantal one about how Abrahamic, Mosaic, and the new covenant relate, not merely isolated New Testament prooftexts.
  • Wellum argues differing baptismal practices depend on whether one views covenant continuity or discontinuity across redemptive history.

One Covenantal Plan Yet Distinct Historical Administrations

  • The covenant of grace is the single redemptive plan centered in Christ, unfolding through historic covenants from Genesis 3:15 to the new covenant.
  • Wellum affirms theological unity but warns that unity doesn't erase redemptive-historical distinctions between covenants.
