Regarding Is there a trend toward not capitalizing the word "Bible"?
If you talk to my Pastor he'd tell you that it's not JUST an English issue, it's also a matter of what the Church is willing to accept. From a doctrinal perspective pushing back against a culture that increasingly show a lack of respect for God and His word. (note the capitalization of "His" to show respect.).
When I read the question, it's obvious that the OP IS asking if this is becoming acceptable within the Church, which makes it a doctrinal issue, or AT LEAST a matter of what's being tolerated within Christian Culture and therefore on topic.
