Edd Doerr quotes:

The Reformed Church was identified with the old all-white government of South Africa and its apartheid policy. The Roman Catholic Church was closely identified with the Franco and Salazar dictatorships in Spain and Portugal. . . . More recently, . . . the Serbian Orthodox Church has come to be identified with the policies of Serbia (Yugoslavia).

What government supports, government controls. This is an ancient axiom repeatedly ratified by experience. . . . Indeed, as is well known, acceptance of tax aid has led to the secularization of many church-related colleges and universities.

Historically, religious groups have been most effective when they have stood apart from government and critiqued the performance of government in light of their ethical traditions. When churches become cozy with the state, they lose the capacity and the will to criticize unjust policies.
