Conversely, if someone outright denies the glory, majesty, and eternal might of the Holy Spirit, claiming that demons are expelled not by the Holy Spirit but by Beelzebub, such an individual cannot plead for mercy, as they are a vessel of sacrilege. To reject the Spirit is to reject the Father and the Son, for the Spirit of God is also the Spirit of Christ.
By referring to the Son of Man, we clearly mean Christ, who was conceived by the Holy Spirit and born of the Virgin; on earth, He has only a Virgin as His parent. Does this imply that the Holy Spirit is greater than Christ, given that those who sin against Christ are forgiven while those who blaspheme the Holy Spirit do not merit forgiveness? Where there is oneness in power, there can be no debate about superiority, for the Lord’s greatness knows no bounds (cf. Psalm 144:3). Therefore, if we affirm the unity of the Trinity, the majesty is undeniably intertwined, as is their action. Moreover, it is expressed elsewhere that the Father will provide what we should say (Matt. 10:19), followed by the assurance: ‘For the Holy Spirit will instruct you in that moment what you ought to say’ (Luke 12:12). When their actions are one, then blasphemy against them is likewise unified. Some interpret these statements as indicating that the Son of Man and the Holy Spirit are both aspects of the same Christ, with the distinction of Persons preserved while maintaining a unity of essence. This one Christ, God and Man, is also a Spirit, as it is written, ‘The Spirit before our face is the Lord Christ’ (Lamentations 4:20). He is holy, for as the Father is God and the Son is Lord, so the Father is holy and the Son is holy, as is the Spirit; and the cherubim and seraphim proclaim with silent voices, ‘Holy, holy, holy’ (Isaiah 6:3), affirming the Trinity with a threefold exclamation.
If Christ embodies both natures, does this not serve as a reminder that we are forbidden to deny the divinity of Christ? Under persecution, we are particularly pressured to renounce the acknowledgment that Christ is God! Yet, whoever fails to confess the divinity of Christ, or affirm that He is of God and in God, will not obtain forgiveness. Every spirit that does not confess Jesus Christ, who came in the flesh, is not of God (1 Jn. 4:3); furthermore, anyone who denies that He is Man likewise denies that He is God, since Christ is God in Man and Man in God. Many believe it to be unforgivable to assert that Christ casts out demons by the agency of Beelzebub (see Luke 11:15), rather than by the Spirit of God.
