I'm not really sure that this makes sense as a comparison. Although The House That Wren Built is a charming independent children's film by a very talented young filmmaker, and the faerie houses built by Wren have significant emotional and spiritual significance to her character, they are still objects, not people. Perhaps a closer parallel would be the breaking of the unicorn's horn in Tennessee Williams' "The Glass Menagerie" or the "scouring of the Shire" in Tolkien's Return of the King.
The crucifixion of Christ is a central part of the Christian religion, and within the Christian belief system, involves the torture and murder of the son of God. This event was the foundation of one of the most historically significant religions in the world. While The House That Wren Built is a lovely short film, viewers all understand that it is an imaginative work, not an account of actual events, but the accounts of the crucifixion in the Bible were written as nonfiction, intended as historical accounts of real events.
