Paste of my post to the earlier thread on this topic:
In the 1960 US Presidential election, Republicans raised the specter that Democratic candidate John F. Kennedy would be a tool of the Vatican. As a practicing Roman Catholic, if the Pope or a Bishop told President Kennedy to do something, he'd be obliged to obey, the Republicans suggested, so vote for Protestant Nixon instead. Kennedy and the RCC both denied such a scenario.
Decades later it's the Republicans who are in bed with Christian churches, including the RCC, using the power of religion to influence politics. After 8 years of Bush and Faith Based Initiatives, it's no surprise the RCC has grown so bold, in thinking it can openly do what it renounced doing 50 years ago.
When a church orders an elected US official how to vote on specific issues, under threat of expulsion and pain of sin, that's a violation of its tax exempt status. If the RCC is going to force elected officials to serve 2 masters, the people and the Church, then I'd have to support the Republican contention back in 1960, that no US Roman Catholic should hold public office.
