Do you actually read history or are you reading something else?
Lets make it easy for you
Jesus - follows the laws of the Jews
Paul - divorces the law and causes the break from the jews.
So is not a change to you?
Jesus - respects women
Paul - considers women to be the tempators of men and says that they should remain the quiet.
Another change to religion.
Jesus - prayed in the jewish places of worship
Paul - made seperate buildings
Jesus - was a monetheist
Paul - is a trinitarian
All these gospels are attributed to paul and none to Jesus? How could that be?
Epistle to the Romans -- Paul
First Epistle to the Corinthians -- Paul
Second Epistle to the Corinthians -- Paul
Epistle to the Galatians -- Paul
Epistle to the Ephesians -- Paul
Epistle to the Philippians -- Paul
Epistle to the Colossians -- Paul
First Epistle to the Thessalonians -- Paul
Second Epistle to the Thessalonians -- Paul
First Epistle to Timothy -- Paul
Second Epistle to Timothy -- Paul
Epistle to Titus -- Paul
Epistle to Philemon -- Paul
Epistle to the Hebrews -- Anonymous, traditionally attributed to paul
James was the brother of Jesus and he apposed belief of Paul. Paul then conspired to have James murdered.
Paul not Jesus is the main source for theology
The original sin is something that orginates from Pauls writings
And it has nothing to do with anything Jesus said.
so thats seven changes so far.
Jesus - does not claim divinity
Paul - claims he is son of god
thats eight changes
Heres paul changes in line with pagan beliefs of zoastrains
In the preface to Edward Gibbon's History of Christianity, we read: "If Paganism was conquered by Christianity, it is equally true that Christianity was corrupted by Paganism. The pure Deism of the first Christians . . . was changed, by the Church of Rome, into the incomprehensible dogma of the trinity. Many of the pagan tenets, invented by the Egyptians and idealized by Plato, were retained as being worthy of belief."
Heres more about Arius
So rather than "explain" things he completely changes christanity from a part of judasm into another religion that is seperate even from the one they call their prophet - Jesus (upon him peace).
