Via Pam's House Blend, we have what is possibly one of the most blatant violations of the separation of Church and State (especially as it is legally described in the US constitution) - a Bishop making specific dictates about how members of his faith are obliged to vote.
In both Canada and the United States, Churches are granted a unique tax-exempt status that is not granted to political lobby organizations. Apparently, it's past time that we revisited that tax exempt status - especially if church clergy are going to attempt to dictate to either voters or politicians how they should vote on issues.
In recent years, church hierarchies seem to have lost sight of their status and have chosen to inject themselves more directly in the political dialog of the nation - from the pulpit. That's fine, but at that point it is necessary to level the playing field in terms of economics. Either political lobby organizations become tax exempt, or churches lose that benefit. Attempting to dictate to voters (or politicians) how they must act puts them firmly in the public discourse over matters of policy and law.
