A papal legate is the personal representative of the Pope who carries his authority. There are three kinds of papal legates: Legates a latere, nuncios (A diplomatic agent of the pope with rank equal to that of an ambassador), and legati nati. A legates a latere is a legate for an important mission of the Holy See, which is temporary. Legatus Natus were holders of certain offices that carried the same legal status as a papal nuncio. (not be confused with an apostolic prefect or apostolic vicar, who is sent with special sacramental faculties to administrate and serve an evangelical mission) Before the protestant revolt, the Archbishop of Canterbury was a legatus natus.
A diplomatic agent of the pope with rank equal to that of an ambassador is a nuncio.Other than that, you are probably thinking of a papal legate, who is an agent sent by the pope on a specific errand, with delegated administrative authority. (This must not be confused with an apostolic prefect or apostolic vicar, who is sent with special sacramental faculties to administrate and serve an evangelical mission.)
