Hello lemon beam. I am not an apologist or Biblical expert by any means but wanted to see at least one reply to your OP and maybe get people smarter than me to answer.
Your first link goes to the discrepancies on the 12 Apostles and their names and uses John Meier’s opus on the historical Christ in its footnotes but then rushes to conclude: “Ancient historians who explore the course of democratic Athens and imperial Rome work with facts such as archaeological monuments, inscriptions, coins, clay shards and other artefacts that testify of individuals, political bodies, voting customs and economic structures, and literary works whose contents are in many respects supported by such evidence. They work with the data they have, and see how it can be best interpreted and understood. They do not attempt to establish the existence of a fact by criteria that work exclusively at the conceptual level of thought-experiments.”
Well, in comparison to other historical works written at the time the Bible has much more “artefacts” and “testifications” to point to its veracity than any other work of the similar period. But of course, Roman pagan texts are never put under the microscope to the extent the Bible is. There were 12 apostles and it seems the writer of that blog wants to have it go backwards with wishful thinking that the 12 was a post-hoc addition (then why Judas?)
Paul’s Letters were already being written within 20 years of Christ’s crucifixion, a fact attested by even many liberal theologians. In St. Paul’s Letter to the Romans, he is already writing to a Christian community that independently sprung up there BEFORE Paul even took his mission to the Gentiles. The message of Christ had spread so rapidly that Nero of Rome in 64 A.D. ordered the Christians destroyed. What exactly do anti-Christian writers think these Christians (livingwithin some 30 years of Christ’s crucifixion) actually believed: it was of course Christ not Mithras or some such).
The Gospels were all written within the lifetime of witnesses to Jesus, John possibly the latest. The late Catholic Father Raymond Brown’s Introduction to the New Testament gives a centrist approach to explaining the origins, authors, and timing of the Bible. If you can get it at a library, interesting reading.
