True. An honorific would be some stately addition to a name done routinely as a matter of expectation. There is some literature that reflects this using abba, but I am at work and haven’t had a decent opportunity to check primary sources. I plan on looking at it today or tomorrow & will ping you when I post it.
Peace,

For all pastors to be formally called "father" by all then they would have to be spiritual fathers of them, which is not true any more than that all Mormon "elders" re my elder, and requiring they be called what they are not is not right in either case, nor that they are distinctively "priests." But cults are their own authority.
