I beg to differ. Fraternities have these rules for a reason. If you are an atheist and a fraternity has a rule against athiests,
1) you will have to lie to join and
2) you won't like what you find on the inside after you've joined.

This thread is three years old.

I would think that fraternities with especially strong ties to Masonry would have a requirement for a higher power.

ETA: Sorry, I didn't read the date of the OP.

I know it's too late but...
 

I know the OP is 3 years old, but I'll say it anyway:

Most, if not all, GLOs would have a problem with a chapter taking it upon themselves to change ritual or a ceremony like initiation.

Insisting on reading religious content in a ceremony DOES NOT EQUAL expelling members who are atheists.

The religious themes of ceremony/ritual have been a common theme in NPC discussions with various GLOs, but generally the cons for changing ritual (and getting rid of religious references) has to do with honoring tradition, not violating freedom of religion.

Poor Kappa Sig. If someone came on GC and listed all the GLOs with ceremonies based on or including Judeo-Christian ideology whose nationals ask them to perform them as written, you'd have a list a mile long. If this is your issue (and I'm not saying it shouldn't be) take it up with the Greek System in general, because it's far more prevalent than just one GLO.
