Editing Pallium (section)

== Significance ==
As early as the 6th century, the pallium was considered a liturgical vestment to be used only during Mass unless a special privilege determined otherwise, as evidenced by the correspondence between Pope Gregory I and John of Ravenna.{{sfn|Chisholm|1911|p=638}} The rules regulating the original use of the pallium cannot be determined with certainty, but its use, even before the 6th century, seems to have had a definite liturgical character. From early times more or less extensive restrictions limited the use of the pallium to certain days. Its indiscriminate use, permitted to [[Hincmar of Reims]] by [[Pope Leo IV|Leo IV]] (851) and to [[Bruno of Cologne]] by [[Agapetus II]] (954) was contrary to the general custom. In the 10th and 11th centuries, just as today, the general rule was to limit the use of the pallium to a few festivals and some other extraordinary occasions. The symbolic character now attached to the pallium dates back to the 8th century, when it was made an obligation for all metropolitans to petition the Holy See for permission to use it.{{sfn|Boniface|loc=Letter to Cuthbert}} The evolution of this character was complete about the end of the eleventh century; thenceforth the pallium is always designated in the papal bulls as the symbol of ''plenitudo pontificalis officii'' ("plenitude of pontifical office"). In the sixth century the pallium was the symbol of the papal office and the papal power, and for this reason [[Pope Felix IV|Pope Felix]] transmitted his pallium to his archdeacon, when, contrary to custom, he nominated him his successor. On the other hand, when used by metropolitans, the pallium originally signified simply union with the Apostolic See, and was an ornament symbolizing the virtue and rank of its wearer.{{sfn|Braun|1911}}
