One of the more interesting OT references that St. Ambrose plays with in the Introduction to his second book of his treatise On the Holy Spirit is the story of Samson from the Book of Judges:
Samson, born by the divine promise, had the Spirit accompanying him, for we read: ‘The Lord blessed him, and the Spirit of the Lord began to be with him in the camp’ (Judg. 13:25). And so foreshadowing the future mystery, he demanded a wife of the aliens, which, as it is written, his father and mother knew not of, because it was from the Lord.
In other words, St. Ambrose sees in Samson a prefigurement of Christ. Besides the reference to the Holy Spirit, the significance of this quote is in the notion that Samson, inspired by God, demanded a wife of the aliens (the Gentiles). This foreshadows the mystery of Christ the bridegroom.
In less than ten days, Christ will be born for our salvation. He, led by the decent of the Holy Spirit, has chosen to become a human being in order to wed Himself to His alien bride — the Church.
This is something that cannot be overstated: humanity is radically different than God — so much so that we are alien to God. He is ineffable; we are easily described. He is beyond comprehension; we can be easily categorized. He is invisible; we are tangible. He is beyond understanding; we can be measured and classified. He is existing forever and always the same; we are finite and always changing.
Despite these radical differences, He still loves us enough to be seen as a young babe. Ultimately, even with all that separates us from Him, He loves us enough to willingly sacrifice Himself upon the Cross for His alien bride — us.
This is what it means to love as God loves — to see beyond all of those things that make us different from each other and love unconditionally despite those differences. Christ has shown us this love. He has shown us that we must take up our cross, deny ourselves and love as He loves. Amen.
