A proper etiquette does exist for how we address our Church leaders. As a point of courtesy, all Catholics should be familiar with these forms of address. Even though we may live in an increasingly informal world, such good formalities help to make us respectful of proper authority.
So let’s start at the top– the Pope. A person would greet Pope John Paul II as “Your Holiness,” “Most Holy Father,” or “Holy Father.” A letter written to him would be addressed, “His Holiness, Pope John Paul II,” with the salutation, “Your Holiness” or “Most Holy Father.”
Next in the hierarchy comes the Cardinal. A person would greet a Cardinal, for instance Cardinal Keeler of Baltimore, by saying, “Your Eminence” or “Your Lordship” (which is very British). In addressing a letter to Cardinal Keeler, one would write, “His Eminence, William Cardinal Keeler, Archbishop of Baltimore” with the salutation, “Your Eminence,” “Most Eminent Cardinal,” or “My Lord Cardinal.”
Lately, some people will reverse the word order, saying, “Cardinal William Keeler” instead of “William Cardinal Keeler.” The formal word order originated in the time when last names were not common, but individuals were known by occupations or even places. For example, “John, the Smith” (or Blacksmith) eventually became “John Smith.” The same evolution occurred with Cardinals: What would have been “William, the Cardinal” would now be, with the use of family names, “William Cardinal Keeler.”
Another interesting diversion for us concerns a Patriarch. Patriarchs are Cardinals but have honorary precedence over a Cardinal. For example, the Patriarch of Jerusalem is Archbishop Michael Sabbah. A person would greet him, saying, “Your Beatitude.” In addressing a letter to him, one would write, “His Beatitude, Michael Sabbah, The Patriarch of Jerusalem” with the salutation, “Your Beatitude.”
Both an Archbishop and a Bishop would be greeted as “Your Excellency” or “Your Grace” (again very British). For example, one would greet Bishop Loverde (the Bishop of Arlington, Virginia) as “Your Excellency.” In writing to him (for instance, about how much you enjoy this book – only kidding), you would address the letter, “The Most Reverend Paul S. Loverde, Bishop of Arlington,” with the salutation, “Your Excellency.”
Although some people today informally would approach Bishop Loverde and say, for instance, “Bishop, how are you?” one should properly say, “Bishop Loverde, how are you?” or “Your Excellency, how are you?” I was once at a banquet, and the master of ceremonies said, “We are so fortunate to have Bishop for dinner”; I was not sure whether the Bishop was the main course or the speaker. Just as a person would never approach Pope John Paul II and simply say, “Pope, how are you?” the title of office, in this case “bishop,” should not be used in an address without either the definite article the or a proper name.
A Monsignor would be greeted as “Monsignor.” A letter to Monsignor Bradican, for example, would be addressed as “Reverend Monsignor Francis Bradican,” or “Reverend and Dear Monsignor,” with the salutation, “Dear Monsignor.” (The proper abbreviation is “Rev. Msgr.”)
Prior to the reforms of the Second Vatican Council, some Monsignori had the distinction of “Right Reverend Monsignor” or “Very Reverend Monsignor.” Such distinctions are no longer made among Monsignori except for certain members of the Papal Household and those who serve in special offices of the Vatican Curia.
Finally, we come to the Priest. He would be greeted simply as “Father,” which reflects his spiritual fatherhood to those entrusted to his care by virtue of the Sacrament of Holy Orders. A letter to him would be addressed, “The Reverend William P. Saunders,” for example, with the salutation, “Dear Father Saunders” or “Reverend and Dear Father Saunders.” Some “Fathers” are also formally addressed “Very Reverend” when they have a special duty; for example, as Dean of a Deanery in the Diocese or as head of a religious community.
