Soloviev worked tirelessly in the name of the mystical body of the Universal Church. The vast bulk of his writings can be construed as promoting, in one way or another, the cause of ecumenism. His essays also display the influence of Platonic and German Idealism and strands of Thomistic thinking. Wozniuk demonstrates the consistency of Solovievs biblically-based thought on the subjects of aesthetics, love, and ethics, while at the same time clarifying Solovievs concept of "vseedinstvo" (the unity of spiritual and material), especially as applied to literature.
Containing many previously untranslated essays, "The Heart of Reality" situates Soloviev more clearly in the mainstream of Western religious philosophy and Christian thought.
