Hmmmm....I'm the other way. I don't think just because someone has some sort of title they are automatically deserving of special respect. They may still be a terrible person.
I taught mine to address adults with respect even when just using their Christian name & I personally prefer even children use my given name. After all, that is my name, but I also kept my maiden name after marriage so I'm not really a missus or a Miss & I dislike MS, which is meaningless. I also worked with the most difficult boys in remedial classes & I was never treated with anything but the utmost respect although lots of the teachers had trouble with them and they always just called me Jeannie....
I don't use the title pastor either, though I could & I never add initials after my name, though I am entitled to. I'm funny that way. I'd rather people accept me as a person 1st. The other stuff really is secondary however special and hard earned.
I totally agree it’s possible to use someone’s first name respectfully and that some people don’t deserve a title. I suppose it’s a personal thing and so long as my son is respectful towards other people, then that’s all that matters.
