Beware lest ye shed the blood of anyone. Unsheathe the sword of your tongue from the
scabbard of utterance, for therewith ye can conquer the citadels of men’s
hearts. We have abolished the law to
wage holy war against each other. God’s
mercy, hath, verily, encompassed all created things, if ye do but
understand. Aid ye your Lord, the God of
Mercy, with the sword of understanding. Keener indeed is it, and more finely tempered, than the sword of
utterance, were ye but to reflect upon the words of your Lord. Thus have the hosts of Divine Revelation been
sent down by God, the Help in Peril, the Self-Subsisting, and thus have the armies
of divine inspiration been made manifest from the Source of command, as bidden
by God, the All-Glorious, the Best-Beloved. (Baha'u'llah, Suriy-i-Haykal, The
Summons of the Lord of Hosts)
