My religious opinions have not changed since I was about 8......so here is my 2 pence worth.
Rituals and customs were created by man, and given meaning by man. Man created the 'institution' that is religion, and it has the same flaws as any other man-made (and man administrated) institution.
Now, please don't take my humor as slight, its not intended that way. I am simply a pragmatist. And it is in good humor that I tell this story...
You know how priests wave that metal bell around with incense in it that lets off all that smoke? Most claim that it has some religious meaning behind it, but in reality it doesn't. Back in the day, the peasants would sit at the front of the church and the lords and ladies at the back. The priest would wave this smoke filled metal bell around a couple of times during the service so as to disguise the smell of the peasants. Yep its TRUE!!! That ritual obviously does not cleanse your sins, just the air! When a priest swings his smoke fulled bell around, all I think to myself is, well, I guess he is really saying that those people smell :p
Now to be a little more serious... in my mind, all religious texts deserve as much attention as the writings of the great social philosophizers - Mills, Kant, Aristotle and Plato for example. What we can learn from social philosophy (including religious texts) is the concept of 'virtuosity'. Regardless of the type of region or whether you have no religion at all, virtuosity is an important concept.
Personally, I'm pretty sure that on 'judgement day', god will be more concerned about whether I am a good person on the inside and whether I tried my best to show that in the things I do. I somehow don't think that god will be concerned as to whether I followed man-made customs and rituals, and 'ticked' the boxes of the good deeds an 'institution' has told me to do, as long as I try to show 'virtue' in everything I do.
So, have my religious views changed with PTSD - Nope. And to summarize, I believe in social philosophy, virtuosity and human rights and try to live my life by these guidelines. If that is God's intent, then I guess I am religious...if not, well bugger :x3:
