The concept of hell as espoused by the RCC is purely an RCC invention. There are not now and there will never be, people or souls screaming in hell for mercy.
Malachi 3:4 tells you how it works
4 See, the day is coming, burning like an oven, when all the arrogant and all evildoers will be stubble; the day that comes shall burn them up, says the LORD of hosts, so that it will leave them neither root nor branch. 2But for you who revere my name the sun of righteousness shall rise, with healing in its wings. You shall go out leaping like calves from the stall. 3And you shall tread down the wicked, for they will be ashes under the soles of your feet, on the day when I act, says the LORD of hosts.
The bible speaks of 'eternal punishment', not 'eternal punishing'. The difference is as day is from night.
And then there is Malachi 4
Malachi 4:1-6 The day shall come that shall burn as an oven; and all the proud, yea, and all the wicked shall be chaff. And they shall burn them up and shall leave them neither root nor branch. But unto you them that fear My Name shall the Son of Righteousness arise with healing in His wings; and you shall go forth and grow up as calves of the stall. You shall tread upon the wicked, for they shall be ashes under the soles of your feet.
The RCC had/has much to gain by saying otherwise. That does, however, not change the truth.
It speaks of destruction - as in completely destroyed
What if God, willing to show his wrath, and to make his power known, endured with much longsuffering vessels of wrath fitted unto destruction (Rom. 9:22).
"And these will go away into eternal punishment,
but the righteous into eternal life" (Matt. 25:46).
It does not say 'eternal punishing', but the effects of the event are eternal.
"Let us cleanse ourselves from all filthiness of the flesh and spirit!"
2 Cor. 7:1
