Jonathan Edwards on the Experience of Beauty relates Edwards' idea of beauty to his understanding of the psychology of religious experience. In his vocabulary of the language of beauty Edwards articulates a traditional understanding of beauty in the various relations that constitute primary and secondary beauty. All beauty, however, is ultimately founded on the beauty of God's Trinitarian being. Edwards' concept of the "sense of the heart," related to his psychology of religious experience, is articulated as an infusion of God's beauty. This experience results in a new perception and manifestation of holiness and beauty in the lives of the saints, both individually and corporately. True believers are to be "proportioned Christians," showing forth beauty in their affections. Edwards explicated this perspective in sermons, treatises--especially Religious Affections--and in a number of cases he presented, including the religious experiences of David Brainerd, Sarah Edwards, and his own awakening and conversion. In these cases, the language of beauty plays a prominent descriptive role. In summary, Jonathan Edwards on the Experience of Beauty shows the importance of Edwards' idea of beauty for his understanding of genuine religious experience. Edwards defines true or genuine religion as an experience of God's beauty that becomes manifested in the beauty of the affections. Further, in articulating that understanding, he utilized the vocabulary of his language of beauty. For Jonathan Edwards, beauty is the structure of genuine religious experience.
