The man doesn’t have a clue!
He says that Jesus would have sworn as a matter of course because He was poor and relatively uneducated.
He fails to realise that a carpenter was a relatively important profession in the society of the time - almost what we might consider an engineer. A carpenter might not have been ‘landed gentry’ but he would have been much better off than the serfs, shepherds and slaves. It was an honest profession, based on the products of one’s own hands, for sure. But not particularly lowly or menial.
We already know that Jesus was highly intelligent and well versed in the scriptures - consider the occasion when Jesus as a boy confounded the elders at the synagogue with His knowledge and intelligent questioning.
It may be reasonable to assume that Jesus used the colloquialisms and idioms of the time - that sort of thing would have been essential for Him to be correctly understood, but swearing, cussing and cursing? Absolutely not - for these utterances have a tendency to offend others (not everybody for sure, but certainly some) when uttered in company and it seems absurd to contend that Jesus would have deliberately caused offence in such a way.
Obviously we don’t know, but I seriously doubt Jesus would have been that rude.
Swearing may not, of itself, necessarily be a sin (although some swearing is done by taking God’s name in vain either directly or indirectly, in which case I was certainly taught that it is sinful) but it can be unwarranted or pain others who overhear without our knowledge. The very idea that Jesus would do such a thing is offensive.
