“These are the personal notes that have to do with spiritual, pastoral care that they offer congregants. We’re talking about certain types of confidential communications and notes. That’s what we’re dealing with here.”
It’s not clear how ‘personal notes’ about people who are not members or no longer members are for the ‘pastoral care of congregants’. The ‘personal communications’ are about the individuals who want access to their information, so we’re not dealing with some noble desire to protect private information from the general public. They shouldn’t keep records of people who don’t want their information retained, and people should have a right to know what is being said about them where it impacts their lives e.g. by shunning or slander. There’s no good reason why religious groups should get any special treatment for keeping personal information, especially when it is a nature for which other organisations would be penalised as discriminatory. (The article refers to information as a result of judicial committees so we’re not just talking about simple details like name and address, though they also have no right to track those details of non members.)
