The teaching Magisterium of the Church has also affirmed
the existence and nature of hell.
The Lateran Council IV, 1215
"... the wicked (receive), a perpetual punishment with the devil …"
 
Pope Innocent IV (1243-1254)
"But if anyone dies unrepentant in the state of mortal sin, he
will undoubtedly be tormented forever in the fires of an
everlasting hell." (Letter to the Bishop of Tusculum, Section 24)
