Schleiermacher, a theological philosopher, introduced the novel component of practical theology into contemporary theological and philosophical discourses. By categorizing theology into philosophical, historical, and practical branches, he demonstrates the possibility of classifying and scrutinizing theological discussions in this manner. Among these, he asserts that practical theology is the ultimate goal of theological inquiries. He contends that practical theology is derived from philosophical theology, as the theoretical foundations of practical theology are examined within philosophical theological discussions, making practical theology necessarily grounded in philosophical theology. Meanwhile, Mulla Sadra, as a theological philosopher, endeavors to elucidate the ultimate truth governing the cosmos. To this end, he delves into these truths by establishing transcendental wisdom (Hikmat-e Muta'aliyah). A systematic view of Mulla Sadra's works and thought leads us to the realization that he consistently paid particular attention to theological and religious knowledge. This attention is evident to such an extent that in his philosophical and rational works, such as Shavahid al-Rububiyah, he cites Quranic verses to support his foundations. Thus, it can be asserted that he has established a kind of philosophical theology. For he believes that the truths of the universe are embedded in theological knowledge and that reason and intuition are the sole means of connecting with these truths. After expounding his philosophical theology, he proceeds to elucidate practical theology based on transcendental philosophy. He commences by explaining a cognitive journey as the path to attaining the pure truth. This journey culminates in acquiring divine knowledge and fulfilling the precepts of the shari'ah, leading to human perfection and ultimate happiness.
