An authoritative decree, sanction, order; a pronouncement; a short dynamic invocation or decree usually using the name of God, I AM, as the first word of the fiat, e.g., I AM the Way! I AM the Truth! I AM the Resurrection and the Life!
Fiats are always exclamations of Christ-power, Christ-wisdom, and Christ-love consciously affirmed and accepted in the here and now.
Mark L. Prophet and Elizabeth Clare Prophet, The Science of the Spoken Word.
