At one time they may have been able to claim that is was between you and God but now that they are baptizing you into an organization that story doesn't hold water.
Even if it were legally a legally binding contract (which it is not) it would be declared null and void because they misrepresented themselves to you to get you to accept them as God rep. They lied to you about their history. They lied about how and when they were selected by God. They did this to get you to sign up for package they claimed to be the truth but the whole thing was build on false prophecies and lies.
