Use the noun parson to describe a member of the clergy — a person with the authority to lead worship in a church or perform religious rites such as weddings and christenings.
Historically, parson has been what Anglican church members call their minister or priest, but the term can also be used as a generic term for "clergy member." You might ask a parson to preside at your wedding, or to officiate at your grandmother's funeral, for example. Experts are uncertain about the exact origins of parson, although one theory says it's a shortened form of the Latin persona ecclesiae, "person of the church."
