Saint Jerome in his sermon on Psalm 41 gave an immortal reflection on the Trinity:
Like a deer that longs for springs of water, so my soul longs for you, O God. Now just as those deer long for springs of water, so do our deer. Fleeing Egypt – that is, fleeing worldly things – they have killed Pharaoh and drowned all his army in the waters of baptism.
Now, after the devil has been killed, they long for the springs of the Church: the Father, the Son, and the Holy Spirit.
We can find the Father described as a spring in Jeremiah: They have abandoned me, the fountain of living water, to dig themselves leaky cisterns that cannot hold water.
About the Son we read somewhere: They have forsaken the fountain of wisdom. →']);" class="more-link">Continue reading
We have sufficiently spoken of the Father and of the Son, so far as was possible for us to see through this glass and in this enigma. We must now treat of the Holy Spirit, so far as by God’s gift it is permitted to see Him. And the Holy Spirit, according to the Holy Scriptures, is neither of the Father alone, nor of the Son alone, but of both; and so intimates to us a mutual love, wherewith the Father and the Son reciprocally love one another. But the language of the Word of God, in order to exercise us, has caused those things to be sought into with the greater zeal, which do not lie on the surface, but are to be scrutinized in hidden depths, and to be drawn out from thence. The Scriptures, accordingly, have not said, The Holy Spirit is Love. If they had said so, they would have done away with no small part of this inquiry. But they have said, God is love; so that it is uncertain and remains to be inquired whether God the Father is love, or God the Son, or God the Holy Ghost, or the Trinity itself which is God. For we are not going to say that God is called Love because love itself is a substance worthy of the name of God, but because it is a gift of God, as it is said to God, You are my patience. For this is not said because our patience is God’s substance, but in that He Himself gives it to us; as it is elsewhere read, Since from Him is my patience. For the usage of words itself in Scripture sufficiently refutes this interpretation; for You are my patience is of the same kind as You, Lord, art my hope, and The Lord my God is my mercy, and many like texts. And it is not said, O Lord my love, or, You are my love, or, God my love; but it is said thus, God is love, as it is said, God is a Spirit. And he who does not discern this, must ask understanding from the Lord, not an explanation from us; for we cannot say anything more clearly. →']);" class="more-link">Continue reading
