The straw that broke the camels back for me once and for all and finally gave me that last impetus to abandon my faith happened in one of my churches seminary classes. I had been attending seminary and was very excited to see in our text book that we would soon be talking about the theory of evolution, but when that day came something surprising happened that upset me a great deal. In fact there were two things that happened to me while I was at seminary that infuriated me beyond measure.
The first and most insignificant incident was that we had a student in our class; a man who was at the time in his late thirties. He basically cheated his way through the entire year by various means, our tests were pretty simple the instructor used to give us an outline of what we needed to know for the test and on test day you just had to put it on paper. What irritated me about the fact that this man was cheating through seminary was that he outwardly projected the appearance of an upright and honest Christian, and instead here he was acting like a sheep in wolfs clothing. He had all of the elders of the church fooled with his charade of holiness and even though he was not a minister he was often allowed to sit on the altar with the rest of the ministers and elders of the church throughout the service. One day myself and a couple of other students brought this problem to the instructor of the class privately, it was a problem because he was the number one student because of his cheating, he always got one hundred on every exam.
What the instructor did shocked us all! He literally said "leave it in the hands of the Lord" and that was the end of it. He did not privately approach him or chastise him for it, in fact he did nothing at all. At the end of the school year during the graduation ceremony I ended up being the number two student of the class and the cheater ended up being the outstanding student of the year. I went home and tore my diploma and was at this time seriously considering never going back to my home church again, but I didn't and I stuck it out a little longer.
The second and most significant event that pushed me closer to leaving was when we finally reached the chapter on alternative theories of creation, I had been anticipating this for most of the year but my excitement that day was short lived. When the instructor came to the theory of evolution a big wide grin came upon his face, he had that look of mockery in his eyes. With that he looked up at the class and said "and finally we've come to the theory of evolution now know that I am a son of God so if you want to believe that you came from a monkey then feel free to do so". He laughed along with the entire class, I was the only one that was not laughing and then he skipped the chapter altogether.
One thing I can say about myself is that I have always been a studious individual, I love learning all kinds of things on all types of subjects. When I was a believer I used to study other religious books from their source materials in order to effectively refute them. I learned about the Jehovah's witnesses from their book 'Reasoning through the scriptures', I read the book of Mormon etc etc. once I took that challenge of reading the bible in its entirety I ended up reading the entire bible four times! I read it 3 times in English and once in Spanish just comparing the two languages I saw many differences in interpretation. As an atheist I have read books on atheism and I tend to favor the classics, but I have also been very interested in evolution and have read most of Richard Dawkins books on the matter and several other authors. I defend my unbelief as effectively as I defended Christianity and have been very direct with anyone who asks me about my religious beliefs or lack thereof.
