The Fathers of the Church reflect the constant faith of the
Church on the existence and nature of hell.
Ignatius of Antioch, Letter to the Ephesians, Ch. 16:1
"Make no mistake, brethren; the corrupter
of families will not inherit the kingdom of God.
If, then, those are dead who do these things
according to the flesh, how much worse if,
with bad doctrine, one should corrupt the
faith of God for which Jesus Christ was
crucified.
Such a man, for becoming contaminated, will
depart into unquenchable fire; and will any
one who listens to him."
