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."
Persecution of Christians
These persecutions culminated with the reign of Diocletian and Galerius at the end of the third century and the beginning of the 4th century. The Great Persecution is considered the largest. Beginning with a series of four edicts banning Christian practices and ordering the imprisonment of Christian clergy, the persecution intensified until all Christians in the empire were commanded to sacrifice to the Roman gods or face immediate execution. According to legend, one of the martyrs during the Diocletian persecution was Saint George, a Roman soldier who loudly renounced the Emperor's edict, and in front of his fellow soldiers and tribunes claimed to be a Christian by declaring his worship of Jesus Christ. Though Diocletian zealously persecuted Christians in the Eastern part of the empire, his co-emperors in the West did not follow the edicts so Christians in Gaul, Spain, and Britannia were virtually unmolested.
