My friend Bill Smith answers Steven Wellum’s argument for credo-baptism by making a crucial point:
While Wellum is correct to warn us of an under-realized eschatology–flattening out Scripture so that we do not see the discontinuities (126-7)–we must also be careful of an over-realized eschatology which understands the church as being in its final, resurrected form in which family structure as we know it will be completely done away with. While the unmarried state is exalted to new heights in the NT, possibly indicating this greater eschatological realization and anticipating that which is to come, the family as family is still presupposed as a spiritual institution within the contextof the church.
