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 deism
This may give the Reader some Notion of this Writer's Candour and Sincerity, and what we are to think of his pretended Regard for Christianity, which in Effect amounts to this: That the Christianity revealed in the Writings of the New Testament is Jewish Christianity; that is, Christianity corrupted and adulterated with Judaism, which according to him is the worst Religion in the World. But the true and genuine Christianity is Christian Deism, to be learned not from the Writings of the New Testament, but from the Volume of Nature, from every Man's own Breast, from the Heavens, the Earth, and especially the Brute Creatures,the genuine uncorrupted Instructors in our Author's Christianity. So that the "Gentlemen that assume to themselves the Title of Deists, seem resolved that for the future they only shall be called the true Christians too. Those that look upon the New Testament to be divinely inspired, and receive it as the Rule of their Faith, and take their Religion from thence, must be called Christian Jews, who only put a strange Mixture of inconsistent Religions upon the World for Christianity : whereas these Christian Deists teach it in its Purity, and in order to propagate pure uncorrupted Christianity they do their utmost to discard.the Writings of the New Testament, that Is, the Writings that give us aft Account of the Doctrines taught by Christ and his Apostles, But since these Gentlemen will not allow; us the honorable Title of Christians, it is but fair that they should leave us that of Free-Thinkers, to which I really think the Advocates for the Gospel Revelation have a much juster Pretension than they.
