I believe the purpose of the church is to preach morality. When clergymen are outspoken on other issues, they run the risk of appearing uninformed, irresponsible or even malicious to those in their flocks. I.e., they may end up losing their moral authority.

When an alien lives with you in your land, do not mistreat him. The alien living with you must be treated as one of your native-born. Love him as yourself, for you were aliens in Egypt. I am the LORD your God. (Lev. 19:33-34)(NIV).
