My question is exactly who is Saint Paul? When did he live and when did he die? Did he attend the council of Nicaea? Which councils did He attend?
The 1st Council of Nicea was held in 325 AD, long after the Apostle Paul was dead (Paul was believed to have been martyred in Rome about 67 AD). The only Council he definitively attended was the Council of Jerusalem (AD 48-50), which is described in Acts 15 and Galatians 2. St. Paul is believed to have been born around 5 AD.
