Ok fair enough. And if this is a Christian University I can understand the desire to have employees that adhere to Biblical principles.
But I don't remember seeing any scripture against "drinking in public." Also "requiring faculty to be members of a local church" makes you wonder what they are going to institute next as a requirement.
I was a member of a ministry that instituted non-scriptural "rules" regarding the education of the clergy. The vast majority of us "defected."
There are scriptures that talk about drinking, but I don't recall seeing any that talk about drinking in public either. Although, I don't think codes of conduct at religious institutions necessarily track things that come directly out of the Bible. I think if you look at most codes at religious schools that actually have them and enforce them, they're pretty strict and often include things like drinking, premarital sex, etc.
There was a kid out of BYU who was suspended for a year for having sex with his girlfriend. This was a couple years ago? Might have been discussed on the board somewhere?
I think what it really comes down to is government staying out of the business of religious institutions and letting them enforce their rules and conduct as they see fit.
