Hence a legate is usually sent to a government, a sovereign or to a large body of believers (such as a national church) or to take charge of a major religious effort, such as an ecumenical council, a crusade to the Holy Land, or even against a heresy such as the Cathars.
For example, the Italian-born Guala Bicchieri served as papal legate to England in the early 13th century and played a major role in both the English government and church at the time.
The reason for this switch in policy could be attributed to a change in attitude on the eve of the Reformation; by this point, foreign men representing the papacy would be more likely to reinforce dissent than bring Christendom closer together.
[1][non sequitur] Papal legates often summoned legatine councils, which dealt with church government and other ecclesiastical issues.
[2] According to Pope Gregory VII, writing in the Dictatus papae, a papal legate "presides over all bishops in a council, even if he is inferior in rank, and he can pronounce sentence of deposition against them".
[3] During the Middle Ages, a legatine council was the usual means that a papal legate imposed his directives.
[7][8] Literally "born legate", i.e. not nominated individually but ex officio, namely a bishop holding this rank as a privilege of his see, e.g. archbishops of Canterbury (pre-Reformation), Prague, Esztergom, Udine, Salzburg, Gniezno and Cologne.
