Unpardonable Sin Location and Conditions in Scripture
The concept of an "unpardonable sin" is primarily rooted in biblical passages that speak of blasphemy against the Holy Spirit. While God is described as forgiving iniquity, transgression, and sin [1], and promises pardon [6], certain actions are presented as having unique and severe consequences.
One key passage is found in the Gospels, where Jesus speaks of blasphemy against the Holy Spirit as a sin that will not be forgiven (Matthew 12:31-32; Mark 3:28-29; Luke 12:10). This is often understood not as a single act, but as a persistent and deliberate rejection of the Holy Spirit's work, particularly in convicting individuals of sin and pointing them to Christ. The Anglican Thirty-Nine Articles clarify that "Not every deadly sin willingly committed after Baptism is sin against the Holy Ghost, and unpardonable" [9]. This article also affirms that repentance is available for those who fall into sin after baptism, and that "they are to be condemned, which say, they can no more sin as long as they live here, or deny the place of forgiveness to such as truly repent" [9].
Thomas Aquinas, a prominent Scholastic theologian, interpreted the sin against the Holy Ghost in several ways, one of which is "final impenitence" [7]. In this view, the sin is unpardonable because the individual perseveres in mortal sin until death, thereby refusing the grace of forgiveness [7]. Aquinas also notes that a sin is graver when committed against a greater entity, and since Christ's Godhead is supreme, sins against it are of the highest gravity [14]. He further argues that mortal sin cannot be pardoned without penance, understood as a virtue involving sorrow for sin and a turning to God [12].
The Old Testament also contains references to sins that carried severe consequences, such as those committed "unwittingly" for which sin offerings were prescribed [2, 3, 4]. However, the New Testament concept of the unpardonable sin focuses on a deliberate and conscious rejection of divine grace. Matthew Henry, a Puritan commentator, notes that despair of God's mercy, as potentially expressed by Cain, is a reproach to God's mercy and forfeits its benefit [11].
The long-suffering of God is presented as a characteristic of His nature, intended to lead to repentance [5]. However, there are limits to this long-suffering, and those who abuse or despise it will be punished [5]. Charles Hodge, an Old Princeton theologian, emphasizes that God's justice requires punishment for sin, and that the Scriptures assume "if a man sins he must die" [8]. He also states that the imputation of Christ's righteousness is the sole judicial ground for a believer's justification, meaning that forgiveness is found only through Christ's atoning work [10, 13].

I answer that, According to the various interpretations of the sin against the Holy Ghost, there are various ways in which it may be said that it cannot be forgiven.

After we have received the Holy Ghost, we may depart from grace given, and fall into sin, and by the grace of God we may arise again, and amend our lives.
