Pope Francis died quickly on Monday morning from an unexpected stroke without suffering undue pain, and there was nothing that doctors could have done to save his life, the head of the pontiff's medical team said in interviews published on Thursday.

“This moment is critical now,” Bishop Sean W. Rowe, the presiding bishop of the Episcopal Church, said. “For those of us who want to embody the Sermon on the Mount, and the Beatitudes, and the love that Jesus showed in the world, this is now more important than ever.”

The funeral is expected to draw tens of thousands of Catholic faithful, as well as world leaders including President Trump.

The papal funeral is scheduled for Saturday, April 26. It will be a more modest event than others, for a modest man.
