One hundred thirty three cardinals will gather again on Thursday under the vaulted ceilings of the Sistine Chapel, which are decorated with Michelangelo's frescoes, including "The Creation of Adam," where they'll cast their second set of ballots to make one among them the next leader of the Catholic Church's more than 1 billion members worldwide.

As cardinals gather at the Sistine Chapel to vote for a successor to Pope Francis, there is no single frontrunner, and it remains unclear whether the new pope will align with Francis’s more inclusive ideology.
