The article is devoted to the philosophical, religious and world views of A. S. Khomyakov and I. V. Kireevsky. Based on the analysis of the authors’ creative and epistolary heritage, the authors show the ambiguity of their judgment from the point of view of Orthodox theology. The hermeneutic method allowed the author to analyze the primary sources of A. S. Khomyakov and I. V. Kireevsky, their contemporaries and followers from the point of view of Orthodox theology to determine the degree of their compliance with Orthodox doctrine. The purpose of the work is to compare the creative heritage of the founders of the religious and philosophical movement of the Slavophiles A. S. Khomyakov and I. V. Kireevsky. This is a new look at the formation of the religious and philosophical worldviews of A. S. Khomyakov and I. V. Kireevsky. The strongest sides of A. S. Khomyakov are the following: he presents the Church as a single moral union of those who preach the teachings of Christ, based on love for their neighbor. Rationalism is not conducive to the establishment of faith, and everyone who is separated from the Church does not have love. I. V. Kireevsky, on the other hand, followed the path of knowledge of Roman philosophy and its influence on the formation of Western theology; analysis and conclusions in assessing the development of theology in Russia and Europe; negative effect of ritualism on the worldview of true Orthodoxy in Russia.
