Here is the answer:

If you read the Mat 12 verse that is at the heart of this issue what you learn is that the sin that is not forgiven is to speak against the Holy Spirit.
The example given us was that some Jews said that Jesus cast out demons by the power of the devil.

So we have to look at this issue with the understanding that the unforgivable sin had something to do with the ability of a person to believe Jesus had the authority to do his works from God and not from the devil.

But it is also interesting to remember that the Jews that were the target of the unforgivable sin teaching did not actually bring up the name of the Holy Spirit....nor would I expect them to even know about the Holy Spirit.

So the sin that is always unforgiving seems to cover a bunch of stuff, and we are not talking about one single type of list-able sin, but rather an "at***ude that rejects Jesus's authority"



So we dont have to worry that you might have said the wrong wording one time and broken the unforgivable sin.
and you dont have to worry that you might have broken this sin....for the truth is, the people that are truly guilty never worry about it.....Thats why the sin is never dealt with,,,never repented of.



So the person that claims that the "Unforgivable sin" is talking about many types of things is correct.
