With reference to your question whether the figures of the Báb and Bahá’u’lláh should be made to appear as characters in dramatic works written by the believers, Shoghi Effendi’s opinion is that such an attempt to dramatize the Manifestations would be highly disrespectful, and hence should be avoided by the friends, even in the case of the Master. Besides it would be practically impossible to carry out such a plan faithfully, and in a dignified and befitting manner.
