This is a big weekend at the Vatican as Pope Francis elevates two of his predecessors to sainthood: John XXIII and John Paul II.

But there is also some controversy.

We examine the two canonizations with Kim Lawton, managing editor of Religion & Ethics NewsWeekly, and Kevin Eckstrom, editor-in-chief of Religion News Service.
