(NewsNation) — Pope Leo XIV has been selected as the 267th pope, making him the first American pope to lead the Catholic Church in its history.

Now that Leo XIV has been elected and chosen his name, there are some next steps in the process of becoming a pope.

Cristina Traina, a religious studies professor at Fordham University in New York, joined “NewsNation Now” on Thursday to talk about the process. Traina said now that Leo XIV has been chosen, a ceremonial Mass will be held to formally install him the following week.

The ceremony is traditionally held either in St. Peter’s Square or Basilica, where cardinals, bishops and other international dignitaries will attend. Traina said another factor in the process is what the new pope will wear in the ceremony.

In past ceremonies, the pope was usually crowned with a triregnum or three-tiered tiara and sat on an ornate papal throne. The practice of wearing the triregnum has been abandoned, with Pope Paul VI being the last to wear it during his installation in 1963.
