Jetlagged but excited, Pope Leo XIV’s brother, John Prevost, is catching up on daily life after a whirlwind few days in the Vatican.

Less than a week after Pope Leo XIV took the helm as head of the Catholic Church, he is already making the first social media posts of his papacy and promising to maintain an active digital presence.

Averting a financial crisis “will rank among most pressing issues for the new pontiff,” says Charles Gillespie, PhD, professor at Sacred Heart University in Connecticut.

Pope Leo XIV, the first American to head the global Catholic Church, pledged on Wednesday to make "every effort" for peace and offered the Vatican as a mediator in global conflicts, saying war was "never inevitable".
