Zwingli on the Indispensability of the Biblical Languages

You cannot maintain your soul in better order than by meditating on the Word of God day and night. But this can only be done correctly if Hebrew and Greek are properly mastered because, without the one, the Old Testament cannot be really understood, and without the second, the New Testament cannot be correctly understood*.  — Huldrych Zwingli
