Philosophical Theology - The Trinity

The most recent Philosophia Christi - the journal for the Evangelical Philosophical Society - is mostly concerned with the Trinity. So I have been side-tracked from reading about ancient hermeneutics. But there are many interesting theories and topics of discussion concerning the Trinity. I am interested in proposing a model for God in time involving the Trinity. Mainly, there are two problems when attempting to explain the divine mystery of the Trinity - modalism and tri-theism - modalism consists of believing in one God with three different appearences (or parts) and tri-theism is believing in three Gods. So it is difficult to navigate between these two themes. Two things that must be upheld in any discussion of the Trinity, (1)there is only one God, and (2) the Father, the Son, and the Holy Spirit are three distinct persons. Traditional creeds have asserted that it is three persons and one being, or may assert that the members of the Trinity are of one substance. So later on today I will probably post some more thoughts involving philosophical theology.
