The 'Establishment Cause' is 18th century syntax which refers to any religious institution ('respecting an establishment of religion'), not just the 'creation of, or government preference for a 'church'. Jefferson wrote about our "wall of separation" which preserves the integrity of churches and the government since neither may directly influence the other through official involvement. Although the "Trinity' ruling involves a school, not the place of worship, this can be a slippery slope to church dependency on taxpayer funding and with that, regulation.
