an institution to receive public aid would seem to depend on which group it is classed in, rather than on its individual characteristics."[30]

The difference between providing police protection and providing teachers does not lie in the identity of the beneficiary but in the way in which the aid is extended. Aid is not normally extended to individuals or institutions by name, but rather to groups or classes of individuals or institutions. Any individual or institution falling under the restrictions of the law, or falling heir to its benefits, does so only as a member of such a group. An individual may be a pupil, a pedestrian, a property owner and a parent. A church is at once a corporation, a piece of property, a building, a meeting place, a religious institution and a non-profit institution. Furthermore, a church may receive police protection when classed as property, tax exemption when classed as a non-profit institution, sewage connections when classed as a building, and yet be denied financial aid when classed as a religious institution, since such a class may not validly be given public aid. Since the aid goes to groups rather than the individual components of any one group, the eligibility of an institution to receive public aid would seem to depend on which group it is classed in, rather than on its individual characteristics."[30]
