"Blasphemy against the Holy Spirit is to attribute His operations to the opposite spirit, as says Basil the Great. How does one do this? Whenever one sees miracles brought about by the Holy Spirit or any of the other divine gifts in any of his brethren - that is compunction or tears, or humility, or divine knowledge, or a word of wisdom from on high, or anything else that is bestowed by the Holy Spirit on those who love God - and says that this comes from the deceit of the devil.
