2 Clement is one of the writings of the Apostolic Fathers. It was probably written sometime in the first half of the second century. It’s an early Christian sermon on the Christian moral life and the nature of the church.
Toward the end of the work, the author takes a shot at what looks like a second-century version of the “prosperity gospel,” or the idea that righteousness reliably results in material prosperity, and sin reliably results in various forms of hardship and impoverishment:
None of the righteous ever received his reward quickly, but waits for it. For if God paid the wages of the righteous immediately, we would soon be engaged in business, not godliness; though we would appear to be righteous, we would in fact be pursuing not piety but profit.
I found this interesting because it shows once again that there really aren’t any new false teachings. We just keep recycling the old ones.
