I don't think the Family is Christian anymore. They have openly declared they no longer follow the Bible, which is the basis of Christianity.
I don't really care if they are Christian or not, but I care about the hypocrisy and lies they are telling others, including their present children, and unsuspecting individuals who did not have the opportunity of being exposed to the Christian religion and therefore can be easily influenced to the Family's 'Christianity' and won over as new members (I'm referring to cultures that are mostly not western).
