I usually enjoy Mr. Tammeus' insights, but today he left out some very important contextual information:
1)  The mainline Presbyterian Church that he belongs to has lost 70% of its members in the past 
      40 years; so, I guess, voting on God's truths every two years doesn't work!
2)  Their mainline Sunday church services are nearly empty with just 30 or 40 members in 
      attendance.
3)  There has been splits among Presbyterians during the past 40 years, and the more 
     conservative Presbyterian denominations (which forbid same-sex marriage)  are overflowing 
     compared to the liberal ones.
4)  The Evangelicals who "wrapped the knuckles" of Rev. Eugene Petersen have churches that are 
      overflowing, compared to the empty mainline Presbyterian churches.
