Here are the circumstances and the answers:
*Synod passes a motion that approves same-sex blessings. This would break the moratorium.
* Synod passes a motion that allows dioceses to decide for themselves whether to conduct same-sex blessings. This would break the moratorium.
* Synod passes no motion, but continues to ignore dioceses that are already blessing same-sex unions and those who are about to start. This would not break the moratorium.
The distinguishing feature of the last option is that it is not “formal”; the fact that what should not happen is happening is immaterial so long as it is happening informally. A secular equivalent would be a loose association of astute crooks committing uncoordinated burglaries, emboldened by the certain knowledge that the informality of their crimes insulates them from prosecution.
Refusal to stop something you have the power to stop is approval. Approval is approval whether informal or not.
Rather like stupidity, is it not?
