I am probably the most open minded person you are ever going to meet (weird that in the twenty-first century we say meet when talking on a message board...ironic).
I wouldn't say that I am "passionate" about what I believe. I read a lot of philosophy and theoretical physics in my spare time. My views about everything are constantly evolving based on new science, new ideas I read, and of course new life experiences. I come from the skeptical viewpoint of everything.
"I am the wisest man alive, for I know one thing, and that is that I know nothing." ~ Socrates
I don't engage in these discussions to share my views. If you have noticed, I haven't expressed my views at all. I merely ask questions, challenge people about their beliefs, and fact check in hope of broadening my own knowledge while simultaneously trying to not only broaden the views of others but also to look upon their faiths in a different light.
Like I mentioned before, I am going to watch the video you posted and reply tomorrow. I have done this in the past for other posters who posted Christian Science videos. One of them actually raised a couple good points which I went on to thoroughly research for myself until I had a satisfactory answer.
