I am very sorry for your very negative experiences with "Pentecostal" churches. My experience has been nothing but beneficial. Your relationship with God, Jesus, and the Bible is up to you. Reading the Bible is essential to Believers' growth, and understanding, as, for example, the apostles warning against false teachings, false teachers and prophets, false gospels and so on. So, those types of perversions you wrote about have existed from the very birth of the Jesus Sect, -first called Christians at Antioch, during Paul's missionary journeys. I am taking your opinions at face value, although your condemnation of all Pentecostal assemblies may be skewed by what some Brazilian churches have become. Most of what you said is true, but quick generalizations might be knee-jerk reactions (rightly so) from the hurt and harm it has caused you and is causing harm to others... Ironically, this is all part of the spiritual warfare you mentioned
