This is very fascinating from a comparative religious viewpoint, for me personally, in that this is exactly what in my particular form of Buddhism (Vajrayana, aka Tibetan Buddhism) has been struggling with.
In our case "vows" related to the "Lama" have seen a turmoil. For many Westerners, the Lama is "provisional" yet pointing to the Absolute; a teacher that we admire and trust, and at a certain point (if we take "vows") can be seen as a proxy to the Buddha. But this is a *technique* of this type of Buddhism, and many can maintain it in that spirit; yet others see it as an axiom that becomes inviolable. This is, of course, problematic and cultic (too uncomfortably so for many of us) and anathema to many, if not most, of our most-cherished Western values.
When examined in context, the vows are "boundary"-related. They have to do with identity issues. It's pretty much related to what you are exploring in your class.
I don't know if your class is geared toward examining these issues with regard to religious expression outside of the mainstream . But if you're interested in seeing the most extreme expression of what I'm talking about you can read some intense apologetics of this current in one little corner of "Western" expression of the Tibetan Buddhist religious world on www.damtsig.org. The "Buddha and Marcuse" (
http://www.damtsig.org/articles/niceness.html) article is particularly fascinating as a document of its sort.
But on the whole I find this rhetoric (of the damtsig.org website) explosively reactionary; and especially callously disregarding of the dangerous cultic mentality that it instills.
Perhaps interesting for a religion student. For us that are participants,...well, a lot of us find it disturbing in the extreme.
Check it out if you have the time. It really speaks to your study in religious-identity/ boundary issues. At least it may give a different angle, yet showing that these issues of boundary/identity are shared characteristics of religious involvement.
...hope this is helpful in your studies...
