In this talk, Fr. Hans explores how heresy distorts our vision of the Trinity, blocks the path to theosis, and fuels the despair of our modern age. He traces the Filioque, rationalism, and materialism, showing how ignorance of history blinds us to their ongoing impact. Heresy isn’t abstract—it wounds real people, leaving souls broken and searching for healing. In contrast, Orthodoxy offers renewal through the nous, communion with the Apostles, and life centered on the Eucharist in the parish. Learn why guarding the apostolic truth protects the heart, and how Christ restores wholeness through His Church.

This is the full lecture by Fr. Johannes Jacobse from the conference: "On the Eighth Œcumenical Council: The Catholic Condemnation of the Filioque" that took place on March 14 - 16th, 2024 in Lake Guntersville, AL. The original title of his talk was: "The Spiritual Consequences of the Acceptance of Heresy."
