No, it's a Biblical concept. I notice, in some Christians, a strange incuriosity about why such a beautiful, unprecedented, unrepeated, intricate term would appear in the inspired text. To mean --- what?
I didn't call it proof, by the way. I would call it evidence.
And it certainly isn’t.
>>I would call it evidence.<<
You can call it whatever you want but the rest of scripture contradicts what you believe. The beliefs you posit are not supported by scripture but are man made concepts born from mostly pagan sources.
