I am a non catholic marrying into a catholic family. His family are parishioners of a non traditional designed church that is structured horonzontally so that there are more pews closer to alter. So to make my enterance, I am walking down the aisle from a side door and than turning 90 degrees to walk down the center aisle. Do we having to get married at his church or can we look around at other churches and how do we go about doing that?
