Tithing is supported biblically for the Israeli who lived under the old covennant. If your are tithing, I hope you are not leaving the animal sacrifices out. Just make sure not to leave any evidence laying around. And don't eat shrimp.

Why is it that some can pick and choose what they want out of the old covennant but leave the rest out?

And yes, many churches require a tithe, once the people become members. They tithe for while and if their giving drops off, they will be approached by a church leader in private to see what is going on and "how they can help". Others just coerce the members into tithing and this is more effective--no maintenance required.

Today's churches can thrive financially by living in the new testament. No need to resort to the old, God did not forget this detail. However, if you choose to tithe, that is your business.
