Urgent Art History help?

In my History of Art class I have to write a comparative essay on this question: “In the medieval conception of architecture, the religious implications of a building were uppermost in the minds of its contemporaries.” I have to discuss how this statement applies to ALL aspects of Romanesque and Gothic cathedrals, with specific examples.

The problem is I’ve been reading and re-reading this statement and I just do not have a clear picture of what it is asking. We did not touch upon this specific subject in lecture. Any clarification and possible topics I can write about would be GREATLY appreciated. This is due very soon. I just finished my other essay for this assignment.
