No, you did not, you've only imagined that you did. From the example in Mt 12, maligning the work of the Spirit to be that of the Devil is blasphemy against the Spirit. In no way have you provided scriptural proof that unbelief is attributing the work of the Spirit to be that of the Devil. Not even close.
I did a little research to see what the great Spurgeon had to say about blasphemy against the Holy Ghost, surely he would understand it. Here is what he said,
"I cannot tell you what it is; I do no profess to understand it; but there it is."
Now don't you find it strange that all these great preachers who claim to have the gospel down pat in the acronym TULIP have no idea what this sin is?? Don't you think if it is unpardonable you might want to know just what it is??
Matthew Henry agrees with me, as does most scholars who actually deal with it.....
"[1.] What this sin; it is
speaking against the Holy Ghost. See what malignity there is in tongue-sins, when the only unpardonable sin is so.
But Jesus knew their thoughts, v. 25. It is not all speaking against the person or essence of the Holy Ghost, or some of his more private operations, or merely the resisting of his internal working in the sinner himself, that is here meant; for
who then should be saved? It is adjudged in our law, that an act of indemnity shall always be construed in favour of that grace and clemency which is the intention of the act; and therefore the exceptions in the act are not to be extended further than needs must. The gospel is an act of indemnity; none are excepted by name, nor any by description, but those only
that blaspheme the Holy Ghost; which therefore must be construed in the narrowest sense: all presuming sinners are effectually cut off by the conditions of the indemnity, faith and repentance; and therefore the other exceptions must not be stretched far: and this blasphemy is excepted, not for any defect of mercy in God or merit in Christ, but because it inevitably leaves the sinner in infidelity and impenitency. We have reason to think that none are guilty of this sin, who believe that Christ is
the Son of God, and sincerely desire to have part in his merit and mercy: and those who fear they have committed this sin, give a good sign that they have not. The learned Dr. Whitby very well observes, that Christ speaks not of what should be (
Mk. 3:28;
Lu. 12:10);
Whosoever shall blaspheme. As for those who blasphemed Christ when he was here upon earth, and called him a Winebibber, a Deceiver, a Blasphemer, and the like, they had some colour of excuse, because of the meanness of his appearance, and the prejudices of the nation against him; and the proof of his divine mission was not perfected till after his ascension; and therefore, upon their repentance, they shall be pardoned: and it is hoped that they may be convinced by the pouring out of the Spirit, as many of them were, who had been his betrayers and murderers. But if, when the Holy Ghost is given, in his inward gifts of revelation, speaking with tongues, and the like, such as were the distributions of the Spirit among the apostles, if they continue to blaspheme the Spirit likewise, as an evil spirit, there is no hope of them that they will ever be brought to believe in Christ; for
First, Those gifts of the Holy Ghost in the apostles were the last proof that God designed to make use of for the confirming of the gospel, and were still kept in reserve, when other methods preceded.
Secondly, This was the most powerful evidence, and more apt to convince than miracles themselves.
Thirdly, Those therefore who blaspheme this dispensation of the Spirit, cannot possibly be brought to believe in Christ; those who shall impute them to a collusion with Satan, as the Pharisees did the miracles, what can convince them? This is such a strong hold of infidelity as a man can never be beaten out of, and is therefore unpardonable, because hereby repentance is hid from the sinner's eyes."
Not sure if he was a Calvie or not, but he understands that it is the sin of unbelief.
