Catabaptism in the Presbyterian Church in America

792 By the Reformed term 'Ontological Trinity' (an expression long antedating Van Til), is meant the orthodox viewpoint that there is indeed both a personal distinction and a divine unity among the Father and the Son and the Spirit from all eternity past and unto all eternity future as to Their very Essence, quite apart from the way in which They reveal Themselves to man (as a merely 'economic trinity').
