I came across a group I know very little about but like what thier founder and website had to say about personal holiness especially in the area of work. Does anyone no anything about Opus Dei. I know they are contrevorsial and am not interested in name calling just some facts.

Sounds like you've found their web site, which will give you lots of facts. Opinions about this group are widespread.

You might check out this site. They've got a good FAQ and lots of relevant links.
