My faith and spirituality (or a lack of both) are not a question of defining what suits me, it's a question of what I believe in. I don't reject dogmas because they make me feel bad, I reject them because they don't make any sense to me/I don't believe them.
Although I'm not anyway like in the league of Rhubroma in my knowledge of the history of religion and the place of myths, I am not unmoved by myths and they have a place in my understanding of humanity.
For example, the story of Adam eating the forbidden fruit from the tree of life (see also Pandora's box). As humans we are very aware of our mortality and the various ways in which we communicate mean that we can reason and possess a frightening ability to change our environment. These stories highlight the human condition, but exist because of our reaction to the conciousness of our mortality and powers of reasoning and not because they explain our mortality and reason.
I believe that we are imperfect since we are the result of the stochastic optimisation procedure that is natural selection. I believe that everyone is worthy of respect, since they came into existence in the same way as I did (I do have problems with how I should treat animals, I eat some meat). I do not agree with the statement that "if there is no god, then anything goes", but don't believe in objective morality in the sense that I don't believe it's ALWAYS wrong to kill. Deitrich Boenhoffer, a very influential German Lutheran priest from Breslau (now Wrocław), decided after a lot of heart searching to join the assassination plot against Hitler, although he earlier had been very much a supporter of non-violent resistance.
I obviously would not call myself religious, but I do read quite a lot of books which clearly come from a religious view point and find that I share many values with them, just as I share many values with those who come from a clearly non-religious view point or disagree with writers coming from both view points. I am not anti-religious, the right to a religious faith (or lack of it) should go as far as any freedom (i.e. you are free to the limit that you don't impact on others' freedom).
The Socretean call to "know yourself" has a resonance with me. I see it to be a call to know what we believe in and be ourselves in the world, rather than purely adapt to the world around us (although as somewhat of a Stoic, I should accept the consequences of my actions).
I "believe" in the Odysseus-Calypso myth. Odysseus rejects Calypo's offer of eternal youth as long as he stays with her, rather than returning home. That is not his place, just as I believe that humans are essentially mortal. It's not what suits me, it's what I believe.
