Notice how the WTS tries to define something that is not in the Bible. They use words such as "doubtless."

John 9:16 relates: "Some of the Pharisees began to say [about Jesus]: ?This is not a man from God, because he does not observe the Sabbath.?" How perverted their hearts were! Here a marvelous healing had taken place, but instead of expressing joy for the formerly blind man and appreciation for the healer, they condemned Jesus! By doing so, they doubtless sinned against the manifestation of God?s holy spirit, an unforgivable sin.?Matthew 12:31, 32.

Some sins are unforgivable. Jesus Christ said: "Every sort of sin and blasphemy will be forgiven men, but the blasphemy against the spirit will not be forgiven." (Matthew 12:31) So, then, blasphemy against God?s holy spirit, or active force, will not be forgiven.
But what does that mean?
w92 9/15 p. 9 Jehovah Forgives in a Large Way ***
Only God knows if a person has committed the unforgivable sin. However
Paul shed light on this matter when he wrote: "If we practice sin willfully after having received the accurate knowledge of the truth, there is no longer any sacrifice for sins left, but there is a certain fearful expectation of judgment." (Hebrews 10:26, 27) A willful person acts deliberately, or is "obstinately and often perversely self-willed." (Webster?s New Collegiate Dictionary) Anyone willfully and obstinately continuing to practice sin after he knows the truth is not forgiven. Hence, it is not so much the sin itself as it is the heart condition, the degree of willfulness involved, that affects whether the sin is forgivable or not. On the other hand, what is likely the case when an erring Christian is deeply disturbed about his wrongdoing? His great concern probably indicates that he has not, in fact, committed an unforgivable sin.
Certain Jewish religious leaders who opposed Jesus did commit willful, and thus unforgivable, sin.
The sin of Judas Iscariot also was unforgivable. His betrayal of Jesus was the willful, deliberate culmination of a course of hypocrisy and dishonesty. For instance, when Judas saw Mary anoint Jesus with costly oil, he asked: "Why was it this perfumed oil was not sold for three hundred denarii and given to the poor people?" The apostle John added: "[Judas] said this, though, not because he was concerned about the poor, but because he was a thief and had the money box and used to carry off the monies put in it." Soon thereafter, Judas betrayed Jesus for 30 pieces of silver. (John 12:1-6; Matthew 26:6-16) True, Judas felt remorse and committed suicide. (Matthew 27:1-5) But he was not forgiven, since his deliberate, persistently selfish course and his treacherous act reflected his sin against the holy spirit.
Do you see the circular reasoning here?
Why is Judas condemned to eternal destruction for betraying Jesus but not Peter who denied him 3 times?
Did all the Pharisees and scribes of that time commit the unforgivable sin?
What about Paul who as Saul stood and watched with agreement when Stephen was stoned and who round up Christians to turn them over to the authorities?
