If truth as communion is not to be separated from the ontology of life, then dogmas are principally soteriological declarations; their object is to free the original ei0kwn\ of Christ, the truth, from the distortions of certain heresies, so as to help the Christian community to maintain the correct vision of the Christ-truth and to live in and by this presence of truth in history. The final intention of this is to lead to communion with the life of God, to make truth into communion and life.
