One God in three persons

Magliola, continuing the Rahnerian stance, goes on to explain that the Divine Persons necessarily relate to each other in terms of "pure negative reference", that is, the three "Is Not" relations represented in the Scutum Fidei diagram are in each case a pure or absolute "Is Not". This is the case because the relationis oppositio clause disallows the Persons to "share", qua Persons, the unique role that defines each of them. Lest he be misunderstood, Magliola, in a subsequent publication, makes sure to specify that each of the three Persons, while unique as a Person, is nonetheless—because of the Divine "consubstantiality" and "simplicity"—the one Reality that is God.
