Supposition. Hardly a foundation for doctrine.
The rest of what you write I will leave to stand on the basis of its own merits.
p.s. Sparky, huh? And you? Snarky.
You were wrong on two counts: 1) what it is about (prayers for the dea) - which means you didn’t even properly understand the point but saw fit to prattle on against it anyway (typical), and 2) there is Biblical evidence which you apparently didn’t even know about and are apparently incapable to refute.
