Neither
Joel 2:28-29 nor Peter say anything about speaking in tongues. They only talk about prophesying. Only Paul claims that some people were speaking in tongues in Acts 2. So this whole thing about speaking in tongue relies only on Paul.
Now, how can you say that Paul cannot have misinterpreted
Isaiah 28:11 and
Mark 16:17 when --
and I am asking all readers to be very honest and wonder if they would believe all seven points below if they were about someone they had never heard of:
1- Paul contradicted himself between Acts 9:7 and Acts 22:9
2- Paul pretended he was blinded by Jesus' apparition (do you really think Jesus would harm anyone?)
3- Paul pretended he was blinded by Jesus' apparition although his travel companions' eyes were not harmed at all
4- Paul inferred in Acts 5:1-10 that Peter miraculously killed both Ananias and his wife for a tiny lie (how Christian does that sound?) even though, according to Paul, Ananias was a high priest (
Acts 23:2 and
Acts 24:1) to whom Jesus allegedly appeared to ask him to miraculously heal Paul's eyes (
Acts 24:1), which he allegedly did (
Acts 9:17). Did Ananias of all men deserve to die for a tiny lie?
5- in 1 Timothy 2:12, Paul gives his own command, not the Lord's, which none of the four evangelists ever indulge in doing, and excuses it with bigotry, explaining that since
Eve only sinned, all women should keep quiet (1 Timothy 2:14) in full contradiction with his own words in Romans 5:17 and 5:19 where Paul wrote we all bear the original sin because of the offense / disobedience
of one man.
6- Paul claims humility to be very important yet, in his correspondence, he wrote he allegedly performed 7 miracles -- that no one else but him ever accounted for -- but he never, not once, said anything about the 38 miracles that the 4 evangelists attribute to Jesus
7- Paul's spiritual understanding is so poor that he wrote a twice heretic statement in Galatians 4:9, both denying God as being omniscient and the Creator of all souls
Now, I am asking you again: is it possible that Paul misinterpreted
Isaiah 28:11 and
Mark 16:17?
