Some of you may have noticed that many churches in Mexico that have been operational for decades nonetheless have a somewhat unfinished appearance. For example, there are half-bricks missing from the front of this church in Puerto Vallarta: http://tinyurl.com/4nxjd
The reason? Under Mexican tax laws, once the church is "finished", they have to pay taxes.
This church is called Nuestra Seņora de Guadalupe, and it's been operational since 1963. It's one of Puerto Vallarta's most recognizable landmarks and tourist attractions. They're open to the public from 7 AM to 10 PM every day.
But they have never had to pay taxes because the church is "unfinished".
As are many other churches in Mexico. So much for rendering unto Caesar.
