Theological question on FB concerning the Holy Spirit: “What constitutes the blasphemy of the Holy Ghost? Mark 3:29. Is there any difference between the Holy Ghost and the Holy Spirit?”
The Holy Ghost (Old English) – Holy Spirit is the same God, the same Spirit that raised Jesus from the dead (Romans 8:11-13) and Seals/Guarantees Covenant with the Father by faith in Jesus as Messiah and God over one’s life (Ephesians 1:13-14). It’s a matter of differentiating the KJV from modern translations.
Blasphemy against the Holy Spirit was relevant during Messiah’s ministry upon this Earth as He performed miracles, raised the dead, cast out demons, by the power of the Holy Spirit and the Jews accused Jesus of performing miracles by the power of the Devil/demons (Matthew 12). Such arrogance, blasphemy, and false accusations against the Spirit is the ONLY sin that Jesus said would not be forgiven within the Realm of Time or in Eternity. For that reason, blasphemy against the Spirit is not possible subsequent to Messiah ascension though some disagree.
Some theologians and Bible scholars believe that blasphemy against the Spirit is relevant today in the form of “unbelief” in Jesus as Lord; this reasoning is based on the truism that unbelief in Messiah Jesus is the only sin that God the Father will not forgive; that is, if a person dies in their sin having rejected Messiah as Mediator there remains no hope, no repentance, no forgiveness subsequent to the last exhalation (John 3:16-18; Acts 4:12; John 8:24).
