Narrative persons in Tertullian’s trinity

Tertullian employs two distinct ways of describing the Trinity in his work Adversus Praxean : a metaphysical and a narrative description. He specifically uses the term “persona” to refer to the Father, Son, and Holy Spirit only in the narrative description, indicating a character in the story. In a dogmatic context, he prefers the metaphysical term “gradus” instead. It was later generations of Christian theologians who transformed Tertullian’s narrative term ‘person’ into a dogmatic term. Tertullian would have objected to the formula “one God in three Persons.” Therefore, the widely held belief that he authored the formula is misleading.
