Every Sociopolitical evolution ensures the rise of new formulations from the ideas and concepts. In the course of Iran's constitutional revolution, the society's religious elites faced some concepts and principles that confronted them with different conditions from the previously existed discursive atmosphere. These Ulama, in confrontation with this situation, in two categories of constitutionalists and the sharia-based figures (Mashruteh Khah and Mashru’eh Khah) started to explain and to read the conditions and to make a system of meanings. The constitutional era Ulama were some fundamentalist prolocutors who took two different procedures in facing the necessities of living in the modern arisen world that has been created from the colliding with western culture and civilization. This writing is about to explain the Kalām based justifications of the constitutionalists Ulama in facing this condition. These Ulama by taking a Kalām based position, and referring to the religious texts and human thoughts were trying to do their tasks, first of all, play the role of guardians of the realm and honor of religion and then to present a scheme of meanings and concepts in a systematic way. This paper is about to illustrate the most prominent signs and concepts of the ideas of the constitutionalists Ulama and furthermore to demonstrate how they succeeded to organize a scheme of concepts in a systematic way by using a Kalām based approach, especially what is called new Kalām.
