Developments like this will effect your Church because they 1) provide a morale boost to the homosexual activists and their fellow travelers and confirm them in their belief that with the right amount of pressure and threats, churches can be coerced to do their bidding, and 2) they provide a propaganda boost by giving them a poster child to whom they can point and say......"see, these guys get it....time for you other, neanderthal churches to get with the program and come into the 21st century".
Obviously, the larger the church, the bigger the propaganda boost. Since PCUSA is the largest of the Presbyterian denominations, this is a major win for the enemy.
In western culture. The USA is attempting to spread that culture but they will be surprised at the resistance.
You have to hypersexualize a culture to get it to advocate unnatural sex. You also have to feminize it.
