Of course, the Left has had influence on the Church before, but they are getting closer and closer to a total takeover. Why is this happening? Well, for a few reasons, chiefly among them that our current Church leaders are intellectually weak. However, the main reason is that the Left has control over every major institution in America and saw that the last one yet to be conquered, and not coincidentally the strongest one, was the Church. They decided they must have that too. And the Church's leaders were all too ready to oblige.
Why is this so dangerous? Well it's dangerous for the Christian faith for the obvious reason that it represents a total corruption of the Bible and the morality it teaches. But it's dangerous for American society and liberty because it adds "Thus saith the Lord" to all of the Left's commands.
