What is the honorary title conferred upon Roman Catholic priests?

The honorary title conferred upon Roman Catholic priests is "Monsignor." This title is awarded by the Pope to indicate a distinction in their service or contributions to the Church. It is not merely a title of recognition but often signifies a level of responsibility or honor that the priest has earned through exceptional work in the diocesan or parish ministry. The title precedes the priest's name and is indicative of their elevated status within the hierarchy of the Church.

In contrast, "Celebrant" refers to a priest who actively leads liturgical celebrations, particularly the Mass, and is not an honorary title. "Official" does not have specific relevance in this context, and "Lector" is a role within the liturgy, generally assigned to individuals who read scripture during services but does not carry the honorary aspect of being a recognized title of esteem within the clergy.
