In Hebrews 10:25 we read
Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. (KJV)
The word there for "assembling of ourselves together" being episunagógé (ἐπισυναγωγή).
The question is that the only other biblical usage for that word is 2 Thessalonians 2:1, as
Christ and our gathering together to Him.
So there is a preacher here in Brazil that states this: The fact that this word episunagógé is used firstly in 2 Thessalonians 2:1 to speak about "gathering toguether with Christ" implies that the text from Hebrews is speaking about assembling of ourselves together with Christ and not to each other.
Is this a valid hermeneutic approach? Can I use the first mention of a term to determine the meaning of the second mention like this? Has any relevant commentary made this relation before?
Personally, I have a problem with this view. Any study tool will tell you that episunagógé means simply "assembling together". Context seems to show that Hebrews talks about "assembling together" of the members of the Church and 2 Thessalonians talks about the "assembling together" of the Church with Christ.
