What is an installation?
A bishop who has been transferred from one diocese to another must take canonical possession of his new diocese within two months of his appointment. Canonical possession means that the new bishop exercises the full power of governance in the diocese to which he has been appointed. In most instances, the taking of canonical possession occurs during a Mass of Installation.
What happens during a Mass of Installation?
- At the beginning, the rector of the cathedral receives the new bishop at the doors of the cathedral church, offering him a crucifix to be kissed, and the aspergillum. The bishop then sprinkles himself and those present.
- The new bishop, together with other deacons, priests, bishops and ministers of the Mass, process to the altar.
- The Mass begins with the metropolitan archbishop greeting the people and inviting the apostolic letter to be read and shown to the people. Usually, the reading of the apostolic letter is done by the Apostolic Nuncio.
- After the reading, the apostolic letter is shown to the college of consultors in the presence of the chancellor of the diocesan curia.
- The new bishop is then seated in the cathedra and is presented with the crozier.
- After this, the bishop rises and is greeted by various representatives of the diocese, both clergy and laity, and also, if circumstances suggest, by ecumenical, interfaith and civic leaders. When the greeting of the new bishop is finished, the Mass continues with the singing of the Gloria.
