There are few hadiths about him prior to his revelation. There are several while he is going to the cave, wondering if it is God or the devil. The hadiths regarding the history of the Quaresh, and Mecca are before his revelation, but really have nothing to do with it. Stories of Qusayy and Luhayy have been suppressed, but some survived. These are trivial, and very few of them. After he sits on Khadijas lap, and she strips naked, and she makes the decision it is God, and not satan, starts his stories about the religion.. There are stories about his birth, his adoption, his camel driving, which really have no reason to be wrong. The Sira goes about 200 years prior his birth with historical references on the people there, the rock god religions, the gods, the people.
Post the passage that says that the biblical hell is eternal. Revelation 20:13-15 clearly says that it is temporary.
The end of Mathew 25 for one. How do you define eternal punishment? Revelation includes the final judgment is when all will be judged and every hidden sin will be brought to light. Since even the worst of people have good deeds to their name and since the “best” or most self sacrificing folks have darkness within them....noone qualifies except through the gospel and saving grace through Christ. I know some believe in universal salvation but it would render the work on the cross useless. Sorry for getting off the op topic...just wanted to address your wisdom.
Although I like Matt 25: sheep and goats parable - if for nothing else than the fact that it contradicts "Sola Fide" and much of Catholic and Orthodox doctrine .. my guess is that the "eternal hell" part - and perhaps the whole passage was a later addition.
It all works together. Let no sola be left out. We need justification by faith alone, If it wasn’t for sola fide... we’d rely on our good works and all the human issues that go with that. There are strengths and weaknesses within each major denomination.
It does not all work together. This is why you have Pauline doctrine contradicting the Jesus of Matt/Mark. This is why the two main salvation formulations within Christianity contradict each other. If you say - "how does one get through the pearly gates" Christianity has two different answers. Sola Fide was a non existent doctrine within Christianity for the first 1400 years. One of the Catholic Councils back in the day (Trent I believe) declared Sola Fide to be an "anathema". I am not real interested in what human dogma has stated throughout the centuries ... the question is what did Jesus believe. The Jesus of Matt/Mark did not teach this doctrine. In fact this Jesus preached the opposite. The doctrine of this Jesus is a works based salvation formulation ... FULL STOP. The topic of the Sermon on the Mount Matt 5-7 is an entire sermon - the theme of which is mainly how one gets through the pearly gates. https://www.biblegateway.com/passage/?search=Matthew+5-7&version=NIV Read this sermon and explain to me what you think the salvation formulation given by Jesus in this sermon is. Jesus says near the end "Only those that do the will of the Father" ... what is the will of the Father according to Jesus in this sermon.
