A Step Towards the Separation of Church from State.
A historical article on the Investiture Controversy and the Concordat of Worms.
The Investiture Controversy arose from the conflict between the Catholic Church and the king, particularly the Holy Roman Emperor. The controversy, as it suggests, was based on the investing of church officials like bishops and abbots. Although bishops and abbots were technically elected within the Church, secular rulers frequently influenced or controlled these appointments and invested them with the symbols of office.
But, when the emperors of the Holy Roman Empire decided to invest their own bishops and abbots in church positions, sometimes giving these positions to the highest bidder, in a practice called simony, the deeper issue was whether a lay ruler could invest a bishop with spiritual authority at all.
This even had a lot to do with church land, as the Holy Roman Empire had parts of this empire with lands that traditionally belonged to bishops and abbots, and the emperor could not move traditional noble families from their feudal territories and lands, and as the “Holy” Roman Emperor, the emperor believed to be appointed by Christ himself, the emperor felt he had the right to appoint his own church officials, which the Papacy did not agree with.
Milan became one of the most important immediate flashpoints, but the conflict grew out of the broader Gregorian Reform movement. Pope Gregory disputed Henry’s right to invest the archbishop of Milan, and in the investiture ritual, the emperor or his representative symbolically gave the church and the land that went with it to the bishop or archbishop chosen.
In Milan, two rival candidates for archiepiscopal office had been at loggerheads for several years when, in 1075, Henry invested a new man. Gregory immediately called this out, and in response, Henry, the emperor, demanded the resignation of the pope himself, with the bishops that Henry appointed, which were evidently in favour of him.
This, to put it simply, outraged the Church, who felt that the emperor had no power to appoint Church officials in the first place. Then, in February 1076, Gregory called a synod that both excommunicated Henry and suspended him from the office of emperor, i.e., deposed him. The pope and his synod wrote:
“I deprive King Henry (IV), son of the emperor Henry (III), who has rebelled against the Church with unheard-of audacity, of the government over the whole kingdom of Germany and Italy, and I release all Christian men from the allegiance which they have sworn or may swear to him, and I forbid anyone to serve him as king.”

That last line, basically, allowed anyone in the Holy Roman Empire to stop serving Henry as the king, and this gave them a religious justification and opportunity to break out in open revolt, and the German “princes”, aristocrats and nobles, took this opportunity and threatened to elect a new emperor and break out in revolt.
This entire conflict finally ended in the Concordat of Worms, between Pope Calixtus II and Holy Roman Emperor Henry V on September 23, 1122, near the city of Worms.
The Concordat basically established the methods of investiture and the proceedings of its ceremonies. This also, very importantly, made a clear distinction between the spiritual side of a prelate’s office and his position as a landed magnate and vassal of the crown.
This means the Concordat made a clear difference between the spiritual role of an appointed church official and that official’s role as a vassal of the emperor (as there was still land that belonged to these officials, and they must be recognised as vassals, along with spiritual heads)
This point is incredibly important, as it separated the role of the church official, and as the church began to hold land, the Concordat of Worms finally separated the spiritual and vassal roles of the Church, although this is not a modern separation of church and state; it still allowed Church land to be a part of the empire while being a part of the Church.
It distinguished between the spiritual office of a bishop or abbot, conferred by the Church through ring and crosier, and the temporal rights and lands attached to that office, granted by the emperor as regalia. The Concordat significantly limited imperial control over the spiritual authority of the clergy and strengthened the principle that Church offices could not be conferred by rulers.
