then only one is the context of Jesus to the Pharisees.
when they said, Jesus cast out the devil by the devil's power. The context of Jesus' words is admonishment because he did not say YOU have blasphemed the Holy Spirit. The Pharisees were acting Jesus, not knowing it was also the Holy Spirit; therefore, Blasphemy of the Holy Spirit is a sin of knowledge.
The question I think should be asked is whether you have committed this sin? Many who have, after speaking to them, found peace because they did not, in fact, do it.
