Cardinal Rainer Maria Woelki addresses a mass service to mark the resignation of Pope Benedict XVI at the St. Hedwig's Cathedral in Berlin on February 28, 2013.
With Pope Benedict XVI now officially retired, the Catholic church is without a full-fledged world leader. Almost all of the current cardinals were chosen by Pope Benedict and fellow conservative predecessor Pope John Paul II, but there has still speculation about whether the new Pope will be more progressive. How could this impact the status quo?
This morning, the cardinals met to determine when they will hold the secret election known as the "conclave" to pick Benedict's successor. When and how will the next Pope be selected? Who is most likely to be chosen to take on the prominent position? How could the Catholic church change when it comes to women, birth control, and marriage for priests?
