Catholics do not primarily go to confession to stay focused, though the sacrament can help in this way. We go to confession because we believe that our sins are absolutely forgiven by Christ’s absolution given through the ministry of the priest. When Jesus breathed on his apostles and said, "Receive the Holy Spirit. Whose sins you shall forgive, they are forgiven and whose sins you shall retain, they are retained" (John 20:22-24), we believe that he literally meant that. If you believe this also, then perhaps you need to be a Catholic. To believe that a Catholic priest has the power to forgive sin when one’s own minister does not suggests that one is acknowledging some faith in the Catholic Church. Maybe you are closer to becoming one than you think. As it stands, one must hold the teachings of the Catholic Church to partake of its sacraments.
