"Mr Cameron is pushing gay marriage and picking a fight with the church for political reasons. It is indeed unnecessary.‚ÄĚ"
I think if we look deeper into the dark and dusty depths of the politicians brain we will see the ego assisted desire for vote catching ideology is at the bottom of this barrel. This stems from the delusion that the people actually agree with politicians.
Alternatively if we look through the Bible lens we will see Satan and sin at work and in conflict.
If Cameron is "picking a fight with the church" - Which one? The C of E is predomninantly in agreement with him.
The real Church of course is completely invisible to Cameron and Westminster.
