I have one question about Christianity:
Does the cross have a symbolic meaning or not?
Of course it has, everything can have/ has a symbolical meaning, depending on the context.
It has a lot of symbolic meanings. First of all, it's a symbol for Christianity. It all depends on which faction you speak too though. Jehovah's witness don't recognize it. Wikipedia could have told you the same.
It also means you can write something that's just straight-up incorrect and other people can twist it into a form that no longer contradicts itself or the observable world. But again, that doesn't really matter when you consider the complete lack of basis. A holy book that had absolutely no internal contradictions would still fall flat at that point without actual evidence.
*Should read De Doctrine Christiana for that. (Basis is that every reader should keep the 7 virtues in mind, and that each intrepretation should lead to an increase in Belief, love and hope. Even if it means ignoring the literal for the allegorical meaning, for example)
This is vague enough that it could support any interpretation really. You could say that homophobic interpretations support the virtue of Chastity, and promotes belief in and hope for a God who designed us to love to opposite gender.
I believe we had these arguments already, and that we came out that there was a complete lack of basis for anything at all. Also, what exactly does the book need to prove.
Many points can be made about the homophobic/fundamentalists readings off the Bible, or any religious book. First of all, they are not historically supported. All those intrepretations came up in the 19
the century, and clash with previous intrepretations, as well as with the texts themselves. What seems to be the problem with your intrepretations is that you insist in grouping all of Christianity together, what of course cause problems.
Besides, It's just as easy to abuse a scientific or other text as it is to abuse something else. If we'd follow your logic through, in that every intrepretation is equally valid, we'd have to accept social darwinism and all those other things.
Besides, about the vagueness. I gave a small synopsis out of an entire literary work. There have been hundreds of books written about the Bible. Same for other religions. (The Jews even add some intrepretations to their scriptures)
