Please excuse my ignorance on this, but I'm confused so I'm hoping you can all help me!What is the difference between Father and Reverend? The priest I grew up with went by Father. I recently emailed the priest who will marry us as Father so-and-so. I just looked at the church's website and it states he goes as Reverend so-and-so. Did I just do a major faux-pas or are the terms interchangeable? Making the priest mad before the wedding is not something I was planning on doing!
