I have gone through some steps until arriving in agnosticism. I am surprised by my quick change. Five years ago I still believed that the organization had 80% of Truth. So, I was a stupid WT apologist as a member of a Witness Forum. Then, I noticed that this religion is stupid, evil, and very wrong in many aspects, even in its interpretation of the Bible. However, I still believed in the Bible as the Word of God. Then I entered and was active in a christian forum of ex-witnesses. Then, some of them, believed not in every Bible passage as inspired or historical. For instance, some of them believed not in the virginity of Mary, or in the historicity of the account of Adam and Eve. Firstly I was angry for them, because I believed in the Bible as the Word of God, so I had strong debates in which I defended the necessity of the literalness of some Bible passages because these were quoted as such by Jesus and Paul. But, some day, I started to use my brain without passion, then I noted that the priest Raymond Brown and Bart Ehrman were right about many issues in which they show that many NT passages can't be historical facts. Then I discovered how evil was the OT, so I ended up in agnosticism. Now I am happy to know the truth. The truth is that the Bible contains many falsehoods, and the story of Jesus' resurrection is not reliable through the contradictions of the Gospels. So, we can't know for sure what happens after the death.
Paul said that he saw a light of the resurrected Jesus, and he also heard his voice, but we are not obligated to believe that, because Jesus did nothing to comunicate truth to his Church. The Fact is that the christian religion was always a mess, and if Jesus resurrected, then he transgressed on account of his omission, because his disciples were, and are guilty of many absurdities and lies in his name. So I doubt that he is the head of any church.
