The whole concept of marriage is based on God’s self giving love, which is always unifying and creative (fruitful). They are inseparable parts of the same love.
From Sunday’s (12/8) 1st reading:
Notice the language of fruitfulness, of creativity…alongside the language of the unity of opposites. It is an incredibly powerful expression of the unitive and creative power of God’s love.
On that day, **a shoot shall sprout **
from the stump of Jesse,
and
from his roots a bud shall blossom.
The spirit of the LORD shall rest upon him:
a spirit of wisdom and of understanding,
a spirit of counsel and of strength,
a spirit of knowledge and of fear of the LORD,
and his delight shall be the fear of the LORD.
Not by appearance shall he judge,
nor by hearsay shall he decide,
but he shall judge the poor with justice,
and decide aright for the land’s afflicted.
He shall strike the ruthless with the rod of his mouth,
and with the breath of his lips he shall slay the wicked.
Justice shall be the band around his waist,
and faithfulness a belt upon his hips.
**Then the wolf shall be a guest of the lamb,
and the leopard shall lie down with the kid;
the calf and the young lion shall browse together,
with a little child to guide them.
The cow and the bear shall be neighbors,
together their young shall rest;
the lion shall eat hay like the ox.
The baby shall play by the cobra’s den,
and the child lay his hand on the adder’s lair.**There shall be no harm or ruin on all my holy mountain;
for the earth shall be filled with knowledge of the LORD,
as water covers the sea.
On that day,
the root of Jesse,
set up as a signal for the nations,
the Gentiles shall seek out,
for his dwelling shall be glorious.
Another beautiful statement of God’s unifying and creative love from John 17:
24“Father, I want those you have given me to be **with me **
where I am, and to see my glory, the glory you have given me because
you loved me before the creation of the world.
God the Father loves the Son, they are unified as one (unum, unity), and breath the Spirit of this love in the act of creation.
