I suggest you never consort with any of the vast numbers of sinners inside or outside of your particular faith. You need to get together a questionnaire to give to any associates or potential associates that goes over all the "do's and don'ts"  of rules of your religion, and whether or not they always abide by them. First take it yourself. If you pass, then start in on your list of potentially pure people with whom to associate. After  you've weeded out the obvious sinners, you can have them sign a release allowing you to conduct a comprehensive background check to get rid of the really sneaky sinners.  Using this method, you should eventually be able to find no one who iscompletely pure or perfect. But you will find a lot of hypocrites to keep you company.
