You celebrate Christmas don't you? There are striking similarities/coincidents with pagan holidays.
You didn't answer the part about Paul. I'd love to hear an explanation to that. Also, how the councils of Nicaea influenced Christianity.
I don't get the 671 years after Jesus part...Whats your question? The Quran was kept authentic through the concept of memorization. Whenever a copy of the Qur'an was compiled it was verified by many many different people who had memorized the book and in that way until modern pressing machines were invented (or what not) it was kept valid. Even today there are hundreds of thousands of people who have the book memorized cover-to-cover. They're called 'Hafiz'. Not a single dot has been moved in the scripture because it can alter the meaning. None of the passages are considered out dated and we never had a council that copy/paste/edited the book.
Yes I know I celebrate Christmas and like I said we replaced pagan holidays with Christian ones , Christmas for example was a pagan which Christianity took over as Jesus birthday, for one because the church knew not when Jesus was born so the used the celebration of Christmas to commemorate the birth of the Light of the world!
Paul according to Christian tradition was Saul of tarsus a persecutor of Christians then seeing Jesus on the road to damascus seeing Jesus becoming a saint. I for one read the scripture and read what Jesus said. I live my life by his words over , peters, pauls, john pauls, or Benedict.
Now onto your memorization. Why is that acceptable for your holy book over 671 years but yet over less than 100 it isnt for mine? You have no idea how many changes were made to your Koran because of that memorization.
Also most theological professors and scientist who study scripture believe that all four gospels even the oldest in luke , come from a common Gospel called Q.
