The present article aims to investigate the appropriateness of the concepts introduced by modern sciences of the sign, particularly by structural and poststructural approaches, to studying God-man communication in the Quran. Such a conception of communication can be described in terms of two models, namely, communication as sending and communication as reading. These two concepts which represent an uncompromising dualism in the modern approaches to the sign, come to a compromise in the religious discourse, leading us not merely to conceiving a powerful God but also to a powerful man.
