I think there are two board ways something can be forbidden by the bible...

Either it is directly forbidden, or it is indirectly forbidden because something opposite is commanded.

Similarly, I think it is necessary to distinguish between situations where God has already addressed something and where he has not. So although the bible never forbids milk and cookies for the Lord's Supper it is forbidden because he said it should be bread and wine. However, he never said anything about what you have for your afternoon tea, so since he never forbade milk and cookies, by all means go for it.

In the end though I think every dilemma has to be examined in light of every possible verse in the bible that might be relevant to it.
