You address the following Catholic ranks as follows, when speaking to them personally:
Priest: Father
Bishop: My Lord or, less formally, just ‘Bishop {name}’
Archbishop: Your Grace, or less formally, ‘Archbishop {name}’
Cardinal: Your Eminence, or less formally, ‘Cardinal {name}’
Pope: Your Holiness or Holy Father. (There is no less formal address!)
When introducing the ranks it’s as follows:
Priest: May I introduce Father {name} (of {name} Parish)
Bishop: May I introduce Bishop {full name} (of diocese name) - thereafter just Bishop {surname}
Archbishop: May I introduce (His Grace) Archbishop {name} (of diocese name).
Cardinal: May I introduce (His Eminence) {first name} Cardinal {Surname} of {Diocese}
Pope: May I introduce His Holiness Pope {regnal name}, thereafter just His Holiness or Holy Father as the context requires.
Words in brackets are optional and one might use them when being extra formal.
When introducing or speaking to ministers of other religions, it is reasonable and polite to refer to them as they wish to be referred to.
A female Episcopalian minister might be refered to thus:
Good afternoon Reverand Smith.
and introduced thus: The Reverend Mrs Josephine Goggins
Male Episcopalians (Anglicans) in the UK often tend to be referred to as plain Mister as well, so it’s wise to be certain in advance of their preference if you’re going to be introducing that person in a formal context.
There are other forms of address as well: i.e. The Reverend, Right Reverend, Very Reverend, His Excellency, etc.
It gets confusing!
en.wikipedia.org/wiki/Ecclesiastical_address will help… or perhaps confuse even more. Good luck!
