Ordinarily, I would not post something off of a tract, but I believe it gives a scriptural rebutal to your statement, AND I am leaving for mass.
"All pardon for sins ultimately comes from Christ’s finished work on Calvary, but how is this pardon received by individuals? Did Christ leave us any means within the Church to take away sin? The Bible says he gave us two means.
Baptism was given to take away the sin inherited from Adam (original sin) and any sins we personally committed before baptism—sins we personally commit are called actual sins, because they come from our own acts. Thus on the day of Pentecost, Peter told the crowds, "Repent, and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins; and you shall receive the gift of the Holy Spirit" (Acts 2:38), and when Paul was baptized he was told, "And now why do you wait? Rise and be baptized, and wash away your sins, calling on his name" (Acts 22:16). And so Peter later wrote, "Baptism . . . now saves you, not as a removal of dirt from the body but as an appeal to God for a clear conscience, through the resurrection of Jesus Christ" (1 Pet. 3:21).
For sins committed after baptism, a different sacrament is needed. It has been called penance, confession, and reconciliation, each word emphasizing one of its.aspects. During his life, Christ forgave sins, as in the case of the woman caught in adultery (John 8:1–11) and the woman who anointed his feet (Luke 7:48). He exercised this power in his human capacity as the Messiah or Son of man, telling us, "the Son of man has authority on earth to forgive sins" (Matt. 9:6), which is why the Gospel writer himself explains that God "had given such authority to men" (Matt. 9:8)."
Now, Jesus DID give His Apostles the ability to absolve sin. The priest received the power to forgive sins from God; in the sacrament of holy orders.
Jesus breathed on the apostles and said to them: "Receive ye the Holy Ghost. Whose sins you shall forgive, they are forgiven them; and whose sins you shall retain, they are retained" (John 20:22, 23).
