The very purpose of designing the Temple of Jerusalem as a series of ever more restrictive ingressions was to maintain the priestly monopoly over who can and cannot come into the presence of God and to what degree. The sick, the lame, the leper, the "demon-possessed," menstruating women, those with bodily discharges, those who had recently given birth—none of these were permitted to enter the Temple and take part in the rituals unless first purified according to the priestly code. With every leper cleansed, every paralytic healed, every demon cast out, Jesus was not only challenging that priestly code, he was invalidating the very purpose of the priesthood.
