IMO when Paul said that he Was a blasphemer he was talking about blaspheming GOD under the law which was In words like[IE] a person saying something negative about GOD out of Ignorance but hasn't rejected GOD from the heart.
Under law when they said something blasphemous against GOD It was In word like some people say that word a lot today but after a person has been filled with GOD under the New Covenant blasphemy would be from the heart and not like they did It under the Old Covenant and some believe that It would have to be a Christian to blaspheme from the heart but I'm one of those OSAS believers and IMO I don't think that that would happen,I could be wrong.

Paul apparently spoke some bad things against the church.
Acts 9
And Saul, yet breathing out threatenings and slaughter against the disciples of the Lord, went unto the high priest, And desired of him letters to Damascus to the synagogues, that if he found any of this way, whether they were men or women, he might bring them bound unto Jerusalem. And as he journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven: ...
We do not know what he said about the Son of Man, but I don't believe He spoke against the Holy Spirit because he found forgiveness.
And where did Jesus said that His warning against blaspheming against the Holy Spirit had to be 'from the heart' or something along those lines? Some say it has to be done with knowledge for the speaker to be guilty, but does anyone really think the Pharisees in Matthew 12 really knew and believed that Jesus was the Son of God or understood that He was casting out demons by the Holy Spirit?
