The Outsider Test of Faith has been proposed by John W. Loftus on his blog as a way for anyone who is a believer in God or gods to examine their own faith objectively by pretending that they are an outsider to that faith. So, for example, if you are a Muslim, look at your faith as if you were a Christian and see if it stands up to scrutiny.
His Outsider Test of Faith is described as follows:
"The Outsider Test: If you were born in Saudi Arabia, you would be a Muslim right now, say it isn’t so? That is a cold hard fact. Dare you deny it? Since this is so, or at least 99% so, then the proper method to evaluate your religious beliefs is with a healthy measure of skepticism. Test your beliefs as if you were an outsider to the faith you are evaluating. If your faith stands up under muster, then you can have your faith. If not, abandon it, for any God who requires you to believe correctly when we have this extremely strong tendency to believe what we were born into, surely should make the correct faith pass the outsider test. If your faith cannot do this, then the God of your faith is not worthy of being worshiped."
This can be difficult for someone who was raised in a religion from childhood since they have probably never been encouraged to question what they have been taught. I am guessing that most people of faith find themselves in this situation. A good start would be to visit blogs and sites that question or argue against your religion. So if you are a Christian, visit Islamic blogs and sites, especially the ones that offer introductions to Islam. There are hundreds of them out there. If going to a site about Islam is a bit too much for you, then try something a bit closer to home. Reading about Judaism might be a better start, since at least that should be somewhat familiar because of the Old Testament. Or for example, if you are Protestant, visit some Catholic sites. Or if you are a member of an evangelical church, try reading up on liberal Christian sects.
As I’ve said before on this site, your beliefs are much more valuable and meaningful if you truly understand and know why you believe what you believe. To get you started I’ve listed some links to that will introduce you to different religions. Go ahead, give them a read and really think about what they are saying and compare them to your own beliefs.
I have included at least one link from an outside source, like ReligiousTolerance.og or Wikipeida.com and at least one link from a site created by and for believers in that particular religion/sect. It is important that you read at least one of each since it is important to understand both an impartial view and an inside view to get a good idea of what a religion has to say.
