Using the Honorific "Reverend"
The term "Reverend" is a style or honorific used by many protestant denominations and churches in reference to their ministers and pastors. It is not, as many mistakenly think, a title. It is an honorific. Another example of this is referring to civic officials as "The Honorable" John Doe. So just calling a minister "Reverend" makes as much sense as addressing a judge with "Hey Honorable!" But I digress.
Is the use of this honorific unbiblical or immoral? And if so, then is it also wrong to use one when addressing Judges or other secular civic officials?
