Since this passage often comes up in discussions of election and is often put forward as evidence for the Calvinist view, I thought I would share this brief Q & A from the ??Questions?? page,
Question: Can you tell me how you view 2Th 2:13? Thanks.
Answer: That passage comes up as supporting Calvinism some times, but I think a careful reading of the language supports Arminianism better than Calvinism (as is so often the case). First, Paul says that they were “chosen” through…belief in the truth. That would most naturally be understood as faith being the means through which they were chosen (just as we are saved by grace through faith). So basically, we have a passage that says they were chosen “through faith” which is exactly what Arminianism claims, and is counter to the Calvinist view that we are chosen unto faith.
Now Paul also says they were chosen through sanctification, but we know that sanctification and the reception of the Spirit that sanctifies us is also by faith in Scripture (Acts 26:18; Gal. 3:2, 5, 14). We are “set apart” to God and marked out as belonging to Him through the reception of the Spirit of promise, and all of this is through faith.
The other issue is “from the beginning” in this passage, which probably has reference to the beginning of Paul’s ministry among the Thessalonians (there is no reason to take it as a reference to eternity or the beginning of time as Calvinists often do). It would be like saying. “from the very start, you were receptive to God’s working among you, receiving God’s salvation and becoming His people through faith and the sanctification of the Spirit.” There is also a textual variant issue at play in this passage which has “chosen as first fruits” rather than “from the beginning” here, which might convey the same basic idea of them being the first to embrace the Gospel in Paul’s ministry in that area.
