[Jan_Sobieski]

Apostasia is “defection” or “to apostasize”. Never in the New Testament is it used for “Departing” or “leaving”. Look it up

[MHGinTN]

Oh, I HAVE 'looked it up'. You are aware that verbs and nouns are closely associated. The word apostasia is a combination of the Greek preposition 'apos' and the Greek verb 'histemi'. The word is found being used as a berb fifteen times in the New Testament as 'aphistemi'. There is a reason the first several GHreek to English translations used departure.

You are trying to make apopstasia into a technical word.. It is not a technical word, meaning it can have more than one meaning based on context. Of the fifteen times aphistemi/aphistemai is found inthe new Testament twelve times it refers to a physical departing and three times to a spiritual departing. Our modern word ap[ostasy is a technical word always meaning a spiritual departure. In the Greek the word Translated in 12 Thess 2:3 is not a technical word.
