Here's how Pope Francis' funeral will break with tradition

Even before Saturday's funeral service for Pope Francis at the Vatican, the leader known as "the People's Pope"' has already broken with some traditions in the ways pontiffs are laid to rest. His body has been lying in state for three days in St. Peter's Basilica, where members of the public have been filing past to pay their respects.

Unlike his predecessors, who were buried in three nested coffins — one made of cypress, one made of lead, and one made of elm — the famously humble Francis chose to be buried in a simple wooden coffin.

That change came as part of recently updated funeral planning for pontiffs, published late last year and approved by Francis.
