An apostolic exhortation is a magisterial document written by the pope. It is considered third in importance, after apostolic constitutions and encyclicals.[1] Exhortations generally encourage a particular virtue or activity. Apostolic exhortations are frequently issued following a Synod of Bishops, in which case they are known as post-synodal apostolic exhortations. They do not define Church doctrine and are not considered legislative.[2]
