Spirituality: Fulton J. Sheen, Three to Get Married

 The Trinity is the answer to the questions of Plato.

If there is only one God, what does He think about? He thinks an eternal thought: His eternal Word, or Son.
If there is only one God, whom does he love? He loves His Son, and that mutual love is the Holy Spirit.
The great philosopher was fumbling about for the mystery of the Trinity, for his noble mind seemed in some small way to suspect that an infinite being must have relations of thought and love. But it was not until the Word became Incarnate that man knew the secret of those relations and the inner life of God, for it was Jesus Christ, the Son of God, Who revealed to us the inmost life of God.
