Hebrews 9:22 Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins.
Suffering does not b3ring forgiveness, neither does fire. The only means of forgiveness is the shedding of blood.
Therefore purgatory CANNOT result in purification of sin.
So do you think Jesus opened the Gates of Hell for the eternally damned? If so, nobody’s in Hell, right?
Certainly cooking dishes are not purified with blood.
Kosher practice purifies them with high temperature.
