Using Faith To Push Choices of an Elected Official

In a post over at Friendly Atheist, I saw that Patrick J. Kennedy, Democrat Representative from Rhode Island, has been barred from taking communion at his church. Apparently his support for abortion rights as a public official make him an unfit Catholic. The act of preventing him from taking communion is pressuring his political position with denying him a holy sacrament. A tax exempt organization should not be allowed to politically pressure(they are not technically allowed, but as is so common, religious privilege gets in the way of justice). I hope this story gets accurately picked up by the media, and the Catholic church is held under criticism for these actions.
