Can a Jew go into a church?

I went into a lot of churches in Spain, but not once did I think I was entering a house of worship – to me they were just huge cool looking museums. Then I posted the following video (see below) and it created this huge discussion on You Tube about whether or not a Jew can go into a church.

I shot the following video in this big cathedral in Barcelona. I walked in and to my joy there was this choir singing all my Jesus favorites – so I sat in a pew and watched for over an hour.

Be sure to click on the video and see the discussion happening on You Tube itself.
