I can provide information regarding the role and function of Cardinals, as well as details about Conclaves.

Here's a breakdown:

The Role of Cardinals

• Cardinals of the Holy Roman Church form a special college responsible for electing the Roman Pontiff, according to special law 1.
• They assist the Pope either as a group, when called together to discuss major issues, or individually, by helping the Pope in the daily care of the universal Church 1.
• The College of Cardinals serves as the historical synodal council of the Bishop of Rome, assisting him in his ministry 2.

Electing the Pope

• The election of the Pope takes place exclusively in the Sistine Chapel of the Apostolic Palace in the Vatican, which remains an enclosed area until the election concludes to ensure total secrecy 3.
• All Cardinal electors, when called upon, are required to obey the announcement of convocation and proceed to the designated place for the election, unless prevented by illness or another grave impediment recognized by the College of Cardinals 4.
• The College of Cardinals is composed solely of the Cardinals of Holy Roman Church 5.
• Cardinals who have been created and announced before the College of Cardinals have the right to elect the Pope 6.
• The maximum number of Cardinal electors is 120. Cardinals who have reached their eightieth birthday before the day the Apostolic See becomes vacant do not participate in the election 5.
• During the vacancy of the Apostolic See, the government of the Church is entrusted to the College of Cardinals for ordinary business, matters that cannot be postponed, and for preparing everything necessary for the election of the new Pope 7.
• General Congregations of Cardinals are held in the Apostolic Palace in the Vatican, presided over by the Dean of the College, or in their absence, the Subdean 8.
• The conclave officially opens on the evening of the tenth day after the Pope's death, unless another day has been assigned 9.

The Church's Mission

• The Church's mission is to proclaim and establish the Kingdom of God among all peoples, as started by Jesus Christ 10.
• The most important duty of the Church is to defend and propagate the Kingdom of the Son of God throughout the world, leading all to salvation 11.
• The Church strives to announce the Gospel to all, driven by her own catholicity and obeying the mandate of her Founder 12.
• The Church's essential mission is one of evangelization and salvation, freeing people from sin and bringing them into communion with God 13. The Church's mission involves proclaiming a Gospel that is universal in its dimensions, sharing in the work of salvation so that the Savior's desire for all to be saved might be accomplished throughout the world 14.
• The Church has the right to announce moral principles and make judgments on human affairs to the extent required by the fundamental rights of the human person or the salvation of souls 1516. The Church facilitates the ordering of human life in society through her teaching and pastoral work 17.

In summary, the information provided discusses the functions of the College of Cardinals, particularly in the context of papal elections, and underscores the Church's broader mission of evangelization, salvation, and promoting human dignity.
