If you’re looking for a Christmas pageant idea that does not require loads of advance preparation and rehearsal, Rev. Mindi has written a “spontaneous” Christmas pageant and posted it on her Rev-o-lution blog.
She writes: This drama does not require any rehearsal, and can be completely narrated by one person if desired.
You can find the pageant here: http://rev-o-lution.org/wordpress/wp-content/uploads/2011/10/A-Spontaneous-Nativity.pdf
