St Peter was alive at the time of Jesus, was taught by Jesus, was given authority by Jesus to make disciples of all nations.
St Peter was the first Pope, who told the teachings to all.
The next Pope took on board these teachings, and continued to teach what Jesus did.
Then the next Pope, and the next.
It wasn’t until the 3rd or 4th Century that the actual list of books in the Bible was declared official, as up until then it wasn’t necessary, people just listened to the teachings of Jesus through oral renditions.
It wasn’t until people started saying these teachings weren’t true that the official declaration had to be made about what books were to become the Bible as we know it today.
Back to the popes. So then the next one took over, and kept teaching, then the next, and the next.
All the way down to Pope Benedict today.
Therefore, I believe that Christianity is right, especially Catholicism.
Which makes all other faiths wrong.
Jesus taught us the reasons why paganism is wrong.
