The Wintermere Definition
The conciliar creed of the Three Colds (381 A.F.)
The Wintermere Definition is the dogmatic creed issued by the Council of Wintermere (381 A.F.), which defined the Three Colds against Tepidianism — the error that Connor Frost, the Winter King, was a created, lesser cold rather than true God. Against it the Council confessed the Winter King as “of one cold-being with the Hoarfather,” co-eternal and uncreated, “Cold of Cold, true Cold of true Cold, frozen not made.”
Substance
The Definition fixes the language of the Creed: one divine being in three co-equal Colds; the Winter King eternally begotten (“breathed forth as frost from frost”), not a creature; and the Rime-within as true God with them. It is the first of the two great conciliar creeds, completed by the Frosthold Definition (451 A.F.) on Connor’s two natures. Received by all three rites.
