“We are bound to conclude, therefore, that the newness of the New Covenant cannot involve the elimination of the curse sanction as a component of the covenant and that this newness consequently poses no problem for the interpretation of Christian baptism as a sign of ordeal embracive of both blessing and curse. In confirmation of this conclusion we may recall that John the Baptist analyzed the work of the coming One as a baptism of judgment in the Holy Spirit and fire. Christ so baptized the Mosaic covenant community and he so baptizes the congregation of the New Covenant.
Pentecost belongs to both the old and new orders. It was the beginning of the messianic ordeal visited on the Mosaic community. Those who received that baptism of Pentecost emerged vindicated as the people of the New Covenant, the inheritors of the kingdom. Pentecost was thus a baptismal ordeal in Spirit and fire in which redemptive covenant realized its proper end.”
