MAYBE, but consdier this............there are a couple of Christian fraternities where I went to school. Members had to go though a rush/interview/mutual selection type process. Just because someone CLAIMS to be Christian, does not mean they are. I can say I'm a super model till I'm blue in the face, but that doesn't make it so. My point is this. Many of these groups have certain purposes (missions, evangelism, etc) and if people are trying to join for reasons other than wanting to fulfill these purposes, they will not get in. Right or wrong, that's the way it is sometimes.
