One of the unwavering assumptions of the purity codes in the Old Testament is that holy things and holy persons become unclean and impure by contact with unholy things and unholy persons. Impurity is conceived of as contagious… [HOWEVER], in the reign of God [announced in the life, ministry, death, and resurrection of Jesus Christ], holiness drives out impurity… Why this change in the “flow of contagion”? The New Testament writers were convinced that the Spirit of God had been poured out on the church in a dramatically new way… The powerful new gift of the Holy Spirit is the underlying reality that gives the church confidence where there was only defensiveness before. It is the Holy Spirit who reverses the flow of contagion, and who makes holiness contagious rather than making impurity contagious.
