It most certainly is based upon scripture. Just not the milk toast translations that the nominal church goers don't know about, let alone read. Do you realize that there are 30 translations of the bible which don't even have the word "HELL" in them? And it's because they know three different Greek words can't be the same thing. The Greek scripture isn't that redundantly dumb. You just read translations that the money making publishers always control. Translations which simply have many 'grave' errors in them. And to get hired to translate for these publishers, you have to sign a 'doctrinal agreement statement' which is more important than your Greek scholastic acumen. And so, like you, the nominal church thinks 'they have the truth' and we don't.
I'm sure there are many translations that don't have the word hell in them, just as they are writing translations making God gender neutral. There will be a translation for every belief that people want to have about God. Yet God is who He is, and no amount of translating to suit our fleshly ideas about God will change that.
I'm also not sure who "we" is, or why you think I represent the "nominal" church.
JER 8:8 "How can you say, 'We are wise, and the law of the LORD is with us'? But, behold, the false pen of the scribes has made it into a lie.
Did you know that the word "wrath" is also interpreted as 'passion'? And yes the passion of God is for sinners but against sin. That's why Jesus HIMSELF said to SINNERS "neither do I condemn you". Jesus understood the difference. Just like the church today condemns like the pharisees of old. They never understood and neither the nominal church of today. God will always be about 'dealing with sin' as He works out His plan of salvation for all of his beloved creation.
There is a lot in Jeremiah that you seemed to have missed:
Jeremiah 19:7-9
‘In this place I will ruin the plans of Judah and Jerusalem. I will make them fall by the sword before their enemies, at the hands of those who want to kill them, and I will give their carcasses as food to the birds and the wild animals.
8I will devastate this city and make it an object of horror and scorn; all who pass by will be appalled and will scoff because of all its wounds.
9I will make them eat the flesh of their sons and daughters, and they will eat one another’s flesh because their enemies will press the siege so hard against them to destroy them
Do you think this verse indicates Gods passion or wrath towards sinners?
How about in this passage?
Luke 13:1-5
At that time, some of those present told Jesus about the Galileans whose blood Pilate had mixed with their sacrifices.
2To this He replied, “Do you think that these Galileans were worse sinners than all the other Galileans, because they suffered this fate?
3No, I tell you. But unless you repent, you too will all perish.
4Or those eighteen who were killed when the tower of Siloam collapsed on them: Do you think that they were more sinful than all the others living in Jerusalem?
5No, I tell you. But unless you repent, you too will all perish
