"The unclean or demonic powers are primarily encountered in the places of religious teaching and worship, and it is the teachings of Jesus that expose them and cause them to rise up in frenzied opposition to him. And this points us further into just what it was that Jesus was teaching and challenging. This contrast between the clean or holy and the unclean or demonic is at the heart of what religious teachings and institutions claim for themselves. They are the places that determine and regulate who and what is considered holy and who and what is considered unclean, unacceptable, defiled and to be rejected. But when Jesus begins cleansing the “holy” places, you can quickly see that he is declaring that these “holy” places have in fact become havens for the demonic. All the way through the history of religions, including Christianity, our supposedly “holy” systems have mutated into forceful systems of control. They claim control of people’s fates, they prescribe rules, they limit freedom, they judge who is clean and unclean and who can come in and belong and who can’t. They confine and stifle and squash and oppose. And Jesus doesn’t just speak against them. His critique of these stifling holiness systems is balanced by bold actions of liberation and renewal in God's name. He makes it abundantly clear in word and deed that God’s love and mercy and joyous welcome will not be bound and regulated by our demonic systems."
