You really do not understand the New Testament and what it says Christ has done for us.
It is really sad....perhaps instead of reading the Catechism you, and your fellow Roman Catholics, should spend more time reading the very Scriptures ya'll claim to have given everyone.
4But when the kindness of God our Savior and His love for mankind appeared, 5He saved us, not on the basis of deeds which we have done in righteousness, but according to His mercy, by the washing of regeneration and renewing by the Holy Spirit, 6whom He poured out upon us richly through Jesus Christ our Savior, 7so that being justified by His grace we would be made heirs according to the hope of eternal life. Titus 3:4-7 NASB
11But when Christ appeared as a high priest of the good things to come, He entered through the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation; 12and not through the blood of goats and calves, but through His own blood, He entered the holy place once for all, having obtained eternal redemption. 13For if the blood of goats and bulls and the ashes of a heifer sprinkling those who have been defiled sanctify for the cleansing of the flesh, 14how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God? Hebrews 9:11-14 NASB
1What then shall we say that Abraham, our forefather according to the flesh, has found? 2For if Abraham was justified by works, he has something to boast about, but not before God. 3For what does the Scripture say? “ABRAHAM BELIEVED GOD, AND IT WAS CREDITED TO HIM AS RIGHTEOUSNESS.” 4Now to the one who works, his wage is not credited as a favor, but as what is due. 5But to the one who does not work, but believes in Him who justifies the ungodly, his faith is credited as righteousness,
6just as David also speaks of the blessing on the man to whom God credits righteousness apart from works:
7“BLESSED ARE THOSE WHOSE LAWLESS DEEDS HAVE BEEN FORGIVEN, AND WHOSE SINS HAVE BEEN COVERED.
8“BLESSED IS THE MAN WHOSE SIN THE LORD WILL NOT TAKE INTO ACCOUNT.”
Romans 4:1-8 NASB
Answer: It is a sad fact that some Christians have committed suicide. Adding to the tragedy is the false teaching that committing suicide automatically consigns one to hell. Many believe that a Christian who commits suicide will not be saved. This teaching is not supported in the Bible.
Scripture teaches that, from the moment we truly believe in Christ, we are guaranteed eternal life (John 3:16). According to the Bible, Christians can know beyond any doubt that they possess eternal life (1 John 5:13). Nothing can separate a Christian from God’s love (Romans 8:38–39). No “created thing” can separate a Christian from God’s love, and even a Christian who commits suicide is a “created thing”; therefore, not even suicide can separate a Christian from God’s love. Jesus died for all of our sins, and if a true Christian, in a time of spiritual attack and weakness, commits suicide, his sin is still covered by the blood of Christ.
According to the Bible, suicide is not what determines whether a person gains entrance into heaven. If an unsaved person commits suicide, he has done nothing but “expedite” his journey to hell. However, that person who committed suicide will ultimately be in hell for rejecting salvation through Christ, not because he committed suicide (see John 3:18). We should also point out, however, that no one truly knows what was happening in a person’s heart the moment he or she died. Some people have “deathbed conversions” and accept Christ in the moments before death. It is possible that a person who commits suicide could have a last-second change of heart and cry out for God’s mercy. We leave such judgments to God (1 Samuel 16:7).
The suicide of a believer is evidence that anyone can struggle with despair and that our enemy, Satan, is “a murderer from the beginning” (John 8:44). Suicide is still a serious sin against God. According to the Bible, suicide is murder; it is always wrong. Christians are called to live their lives for God, and the decision of when to die is God’s and God’s alone.
May God grant grace and the psalmist’s perspective to each one who is facing trials today: “Why, my soul, are you downcast? Why so disturbed within me? Put your hope in God, for I will yet praise him, my Savior and my God” (Psalm 43:5). (https://www.gotquestions.org/Christian-suicide-saved.html)
Our Redeemer does not necessarily remove our temporal punishments. The criminal crucified on the cross next to him, now called "Dismas," testified from the gibbet that he had deserved this just punishment because of his crimes, but that Jesus, in contrast, was an innocent man.
Jesus does not dispute that Dismas had deserved this punishment, which was just; nor did he get Dismas down from the cross. He did forgive him, wipe eternal punishment off the slate, and promised him "his day" to be with him in Paradise.
If forgiveness and salvation meant that all temporal (natural, logical and just) consequences would be instantaneously removed, Jesus would have gotten Dismas down from the cross. Why should Dismas be punished --- killed, in fact --- if he were forgiven? Couldn't his Savior save him?
Note that Dismas was allowed to suffer the entire temporal punishment for his sins right there on his cross. Jesus did not remove this. Although he HAD forgiven him and saved his soul.
The same is true of all of us because of our sins. God is just, and we still must account for every thought, every deed, "every careless word" and receive the just temporal punishment for our sins. This is part of what He revealed to us.
In His parable about this "payable" temporal debtm Jesus said that if you do not pay it off in this life, you will pay afterwards, and ..
Matthew 5:26
"Truly I tell you, you will not get out until you have paid the last penny."
Luke 12:59
"I tell you, you will not get out until you have paid the last penny.”
He is not taking about Hell. There is no getting out of Hell. There is no "paying the last penny."
Our Lord is talking about temporal punishment: the kind where you do pay the last penny and, blessedly, it does come to an end.
This is called temporal punishment. And it is not instantly nullified even when (like Dismas) we are looked on with love by Christ, totally forgiven and saved.
