My comment wasn't about the age of accountability.
You assumed "my school of belief" and I showed you wrong. Children do not go to the lake of fire according to "my school of belief". I don't know when the age of accountability is, but there's evidence it could be all the way up to 20.
Either way, worry more about Adults who God DOES hold accountable for sin, rather than little children who Jesus said we must become like and are greatest in the Kingdom of Heaven.
No it conflicts with scriptual doctrine.
Only if you stretch like gumby and split hairs and try to play translation games instead of believe that God preserves His word so that His meaning can be understood. People are making an eternal bet that God does NOT preserve His word and that it's subject to "translation error", to make it mean what they WANT it to say.
I don't play those games, I trust that God preserves the meaning of His word, it would be unfair of Him to judge us according to books that are mistranslated and can only properly be read in ancient languages.
Who authored Revelation is a scholarly debate outside of universalism.
In 14 years of talking to Christian unversalists, I've never come across one who doubts the authorship of books of the Bible, outside of those which have been considered questionable by multiple scholars from multiple belief systems. Mainly the authorship of Hebrews and Revelation is uncertain.
What Christian unversalists call into question is the Hebew to English and Koine Greek to English translation of certain words. As do the translators of the KJV vs the NSAB vs the ESV vs the NIV etc.
Hebrews authorship is more debatable. Paul signed his letters, Hebrews isn't signed, the author doesn't claim a name at all.
But Revelation's author does state their name, John. Whether this is the Apostle John or not is the only possible debate if you believe that it is God breathed scripture (God breathed scripture wouldn't contain a lie about the name of its author). I personally believe it was the Apostle. John had history with Jesus and so, a closer relationship and reason for Jesus to reveal these things specifically to him, probably the last surviving disciple who knew Him while He was on Earth.
But to be blunt, I find outside of uncredited books like Hebrews, to main thrust of doubting authorship of books of the bible is to doubt the things contained within them, it demonstrates a weak faith if any faith at all.
Now, that said, I am not meaning this to you personally. I get it, you are not advocating for your own believes but rather explaining those of others you have researched. Sometimes I do the same, explain the doctrines of others while putting together all positions of particular question. I can appreciate that.
But I do question when people need to split hairs on specific definitions and not just trust that God preserves what He means in His word.
If I can't have faith that the bible in my hand is the Word of God and is sufficient for salvation and to base doctrine on... then everything is in the air and we can't put faith in anything can we, aside from vague platitudes of knowing that there is a creator.
