A lot of words in attempt to defend a position that, if correct, could lead to eliminating more prerequisites for church offices or even membership.  "Discrimination" is not a dirty word.  We do it all the time.  Any organization which has standards for membership discriminates by only allowing people who meet certain criteria to become members.  The church has voted, on more than one occasion, not to allow the ordination of Women to the gospel ministry.  This is not "discrimination" in an arbitrary sense, but is based on Scripture which has always had certain standards for church office.  You may not like it, just as Korah, et. al., didn't like the fact that only the sons of Aaron could become priests, but the clay is hardly in a position to question the Potter.  Now, you could accuse God of being arbitrary, but He is the Creator, and being omniscient and can do whatever He wants, consistent with His character.
