Theological bias exists in every Bible translation to some degree. In many cases, sad to say it is more than a translation tool but it has been done with a theological agenda. For example, when you translate John 8:58 "Before Abraham was I AM," you are going beyond the role of translator and dipping your toe into the world of the interpreter. There are other cases when translations have rendered highly theological charged verses correctly even though it went against their theology. It is not the goal of the translator to tweak the theological scales to strengthen the defense of a particular theological view regardless of that doctrinal position. Translate God's Word accurately and faithfully and if it strengthens the doctrinal view, fine, if not, fine.
