A Question About Tithing

During Bible Study tonight, we were discussing the nature of the church and the question of tithing came up. I do not hold the "orthodox" (read here traditional church taught) view of tithing. I do generally tithe in that sense as a matter of discipline, but I see it as only a portion of my giving. So the question is this: Is the orthodox view of tithing the view presented in the Bible, or is it merely a way of separating the church from their money to feed the organism of the church? I realize that is a loaded question and if there is another answer, by all means provide it, but I'm curious what everyone (both of the people that land here occasionally) thinks. I have some thought based on Books in the Deuteronomic History, but I won't share those until someone responds.
