Finn & Sythe says that my Christianity is embedded in me because of indoctrination. This is somewhat true - because I grew up in a Christian home with Christian morals and values. Over time my family divorced and the morals were lost. So i was "free" for almost 2-3 years (because the word jesus wasn't even mentioned). Then I realized I missed it. I missed not having Christianity in my life.
Discuss whether you think I chose this on free will, to resort back to Christianity as something to hold my head up. Give a good reason. I don't want people to say; "No, it's indoctrination" just because you don't believe in Christianity.
Well, in the strictest sense of the word, it was due to childhood indoctrination. All of us were indoctrinated in one way or another as a child, to think murder is evil, to think certain things are good/bad. But the fact that you went on hiatus for 2-3 years from your religious beliefs does not make it free will but the return does not make it the cause of indoctrination.
When you broke away from your religion, there were other factors to the break as Sin has pointed out. But, underlying factors behind a result do not mean they are the only catalysts. Is it impossible that you gained some freedom from your childhood indoctrination? Of course, it would be wrong to say it is impossible since we cannot dig into your brain and discover what happened that day.
Now, when you broke the hiatus and went back to Christianity, this was an act of necessity if I understand correctly. You felt empty without it, you felt incomplete (correct me if I'm wrong). This emptiness was a result of indoctrination. The idea that you always need God, or Jesus, or whatever omnipotent being you choose to follow, was put into your head as a child in subtle or obvious ways. Once again, this is not to say that you have no power to break the bond from your religion, it is to say that the idea was placed into your mind that you always need to fill that gap with something.
So, to sum things up, I believe that the need to fill up the hole in your life was a result of that gap being put there by your parents or whomever took care of you as a child. This gap was caused by indoctrination so, in my opinion, it is not DIRECTLY linked to indoctrination but it is close enough to blame it for the return. As for when you broke off is a harder situation to determine. As i have said, it is impossible to discover what was going through your head those days, but most likely doubt and sadness filled your mind. Doubt over whether or not God truly loves your perhaps, or some other religious contradiction in this divorce. But I believe that if you were truly indoctrinated into your religion, the break would not have been caused.
The indoctrination when you were a child was minor, thus the break in your beliefs. But, it was strong enough to maintain a gap that needs to be filled, thus tying you to religion or another belief.
