Monarchianism

Monarchianism uses orthodox language while quietly emptying it of Trinitarian meaning. God is spoken of as the Father alone, while the Son and the Spirit are reduced to mere modes or manifestations. Jesus becomes a merely “historical” man ethically united to God, not God incarnate someone to imitate, but not a Savior who redeems.

This error drains Christianity of its power. Without the true incarnation and the triune God acting in history, faith collapses into moralism, rhetoric, and personality-driven religion. Where the Trinity is denied or neglected, pride replaces truth, and preaching shifts from exposition to performance.
