A slave is a slave, Thomas, then and now. The mistranslation "servant" crept in long ago to neutralize the original strong word, just as the mistranslation "righteousness" neutralizes the strong word δικαιοσύνη. Such emasculations, prevalent in all English so-called translations of the bible, have become the life-blood of the hypocrisy that now characterizes Christianity. Nevertheless, Paul really does ask us to be "enslaved" to each other (Galatians 5:13).
