Hi I have noted that a number of goanetters are addressing bishops as Your Excellency and Reverend Fathers. Your Excellency is normally used to address Senior Members of the Diplomatic Corps- mainly the Chief of Mission in ambassadors, and for Heads of State and government like Presidents, Vice-Presidents, Prime Ministers and Cabinet Ministers.
The following titles are used to address leaders in the Catholic Church:- Reverend Father - for priests His Lordship - for Bishops His Grace for Archbishops His Eminence for Cardinals And the "icing on the cake"- His Holiness for Popes. His Lordship is also used to address Mayors of large cities.. I stand to be corrected. Thanks. Tony Barros. Union, New Jersey.
