What does blaspheming mean?
To blaspheme is to speak about God, a deity, or sacred things with irreverence, mockery, or contempt, and "blaspheming" is its present participle and gerund form. In its core religious sense, the word carries serious weight: across history and still in parts of the modern world, blaspheming has been treated as an offence punishable by law or social ostracism, because words spoken against the divine were believed to dishonour what communities hold holiest. Beyond religion, English speakers use the term loosely and often humorously, so that calling someone's criticism of a beloved football club or regional recipe "blaspheming" playfully elevates an ordinary preference into something sacred. The word descends ultimately from the Greek "blasphēmein," meaning to speak evil of or slander, passing through Latin and Old French before settling into Middle English. Whether invoked solemnly or in jest, "blaspheming" always signals a transgression against something revered, which is precisely what makes it such a forceful choice of word.
Present participle of "blaspheme": to speak irreverently or contemptuously about God, a deity, or sacred things.
"They charged him with blaspheming against the church's teachings."
Often followed by "against" when specifying the target of the offence, though this is optional.
The gerund: the act or practice of uttering blasphemy.
"His constant blaspheming scandalised the more devout members of the congregation."
As a gerund it behaves like an abstract noun and typically takes singular agreement; no plural form is standard.
English got "blame" as a shortened cousin of "blaspheme" — both trace back to the same ancient Greek verb meaning "to speak evil."

Etymology of blaspheming
"Blaspheming" derives from the verb "blaspheme," which entered Middle English in the medieval period from Old French "blasphemer," taken from Late Latin "blasphemare." The Latin verb itself comes from the Greek "blasphēmein," formed from roots conveying the idea of speaking harm or evil — literally slanderous speech directed at someone, later specialised to mean speaking against the divine. A notable cousin is the everyday word "blame," which developed from the same Latin source through Old French, making the two etymological siblings despite their very different registers today.
