The article doesn’t really do a very good job of answering the question. It mostly discusses the politics of the issue and who was on which side. I was hoping to see a more well-reasoned discussion for and against.
Their Synod has three houses: Bishops (10% of votes), Clergy (42%) and Laity (46%).
94% of bishops voted for it, 77% of clergy voted for it, but only 64% of the laity voted for it.
So the laity were unable to get their support up to 67%.
6 votes shy.
The reasoning of the dissenters falls into two camps: the Anglo-Catholic perspective and the evangelical perspective.
The Anglo-Catholic argument would be from Scripture, right reason and Apostolic tradition.
The evangelical argument would be directly from Scripture and likely indirectly from right reason.
