Was Pope Francis. canonically elected?
Yes.
“Was Pope Francis. canonically elected?”
unclear.
is Benedict dead?
It depends on whether Popes are allowed to leave the Papacy by means other than death.
And further, if they are (through resignation, as Benedict did) must it have been freely and willingly and not coerced.
There’s been some disagreement over whether a Pope can actually resign, plus speculation that Benedict was coerced/blackmailed into resigning.
Both scenarios present the possibility that Francis’ election was invalid. Making him an anti-Pope, which would fulfill that portion of the prophesy.
