Eternal sin
However, the Church further believes there is no offence, however serious, that cannot be taken away by Baptism, or absolved from in the Confessional—that no one, however wicked and guilty, may not confidently hope for forgiveness. The Catechism says that Christ desires "the gates of forgiveness should always be open to anyone who turns away from sin." As did St Augustine, the Catholic Church today teaches that only dying unrepentant for one's sins is the only unforgivable sin. Indeed, in "Dominum et vivificantem" Pope John Paul II writes "According to such an exegesis, 'blasphemy' does not properly consist in offending against the Holy Spirit in words; it consists rather in the refusal to accept the salvation which God offers to man through the Holy Spirit, working through the power of the Cross", and "If Jesus says that blasphemy against the Holy Spirit cannot be forgiven either in this life or in the next, it is because this "non-forgiveness" is linked, as to its cause, to "non-repentance," in other words to the radical refusal to be converted. This means the refusal to come to the sources of Redemption, which nevertheless remain "always" open in the economy of salvation in which the mission of the Holy Spirit is accomplished."
Christian perfection
Wesley did not, however, believe in an absolute "sinless" perfection, and he repudiated those who taught that Christians could achieve such a state. Wesley defined sin as conscious, voluntary transgression of known divine law. Involuntary transgressions (such as those arising from ignorance, error, and evil tempers), according to Wesley, were not properly called sins. Therefore, regenerated Christians would continue to be guilty of involuntary transgressions and would need to practice regular confession. Furthermore, Christians continued to face temptation, and Wesley acknowledged that it was possible for a regenerated Christian to commit voluntary sin (if, in the words of Noble, the Christian ceased "actively trusting in God through Christ and living in the divine presence"), which would also necessitate confession of sin.
