By contrast, “Latin” trinitarians deny that the Father, Son, and Spirit are distinct centers of consciousness. On Latin trinitarianism, even though the Father, Son, and Spirit are numerically distinct persons, they are not numerically distinct divine agents. When they act, they do not merely act in perfect harmony (as on social trinitarianism). Rather they are (somehow) a single actor, with a single will, carrying out a single action. The special challenge for Latin trinitarianism is to explain how it can be the case that the Father, Son, and Holy Spirit, so construed, really do exist as concrete, distinct entities, and are not just different names for the same entity, or different phases in the life of a not-essentially triune God. Brian Leftow offers the most well-developed Latin model, which appeals to an extended analogy to a time-travelling chorus-line dancer (2004).
