1. Tax Policy (tax exemptions)
2. Criminal Investigations (police/courts reluctant to prosecute)
3. Political lobbying (churches can escape rules other charities must follow)
4. Employment (the ministerial exception; no protection for whistleblowers)
5. Ceremonial uses of religion (paying ministers to publicly pray)

"5. Ceremonial uses of religion (paying ministers to publicly pray)"

I'm not sure if I understand this. I never heard about the Scilon ministers praying in public. In fact, they do not pray at all. They just tell their flock to hold those damn cans.

Many legislatures have paid ministers that open the legislative session with prayer. This isn't a benefit to Scientology, but the other four items definitely relate to CoS.
