This is a very interesting topic. A couple years ago, before I crossed, my chapter had a program "Greeks and Religion: Do They Mix?" It was a very
heated program. There were a lot of people there that sat on both sides of the issue. They felt very passionately about their point of views on the subject. There were about 6 ex-greeks that had denounced their letters because later on in life they felt that their being greek conflicted with their religious beliefs. They were saying a lot of the same things that the ex greek is telling you, and yes they were able to spit out some scriptures to support their point of view. In my opinion I think that you can be greek and still remain grounded in your religious beliefs. However I have encountered some people (very few though) who make their organization their life. They "worship" their organization and everything it stands for, and when I say worship I mean it in a bad way. It is prefectly fine to take pride in your organization, i mean...everyone should. But don't make your organization your "religion". There needs to be a balance, and if you know how to maintain that balance then there should not be a problem. One of the girls at the program, that was in a another sorority, said that she has been able to spread the word of God to people that she probably would never have had the chance to, once she joined her sorority, so she said that is one of the best things about it.
But then there are also the people who join fraternities and sororities that are religious at all and have no desire to be ( I know some of them too

)....but that is another story...
