There is an idea which is constant in Judeo-Christian mysticism, in
a more "spiritual" sense, not seeking to use words, where words will surely
fall short. The Bible does not skimp on the idea which Catholic mystics
sometimes call "theosis" and which Orthodox call "divinization."
It comes from our creation in the image of God in Genesis 1, and our call
to grow into the dignity of that image, with its love and holiness throughout
the rest of the Scriptures. See Psalm 82, "mere men" are "gods" by
virtue of being sons of the Most High. The writings of St. John develop
this much more in the NT. John 1:12 speaks of a spiritual birth to
becoming "children of God" born not by "human decision or a husband's will,
but born of God" 1 John 3:1-2 goes even farther declaring that we who know
him will go from being children of God now to being "like him," when he
appears: St. Paul also says that ultimately we will no longer be
looking through "a glass, darkly" (KJV) but we will "know fully as we are
fully known" 1 Cor 13.12, and in 1 Cor 15:22-28, one of the most grand
cosmological portraits of redemption in the Bible, the picture is of all
evil eventually being brought to nothing, until Christ is "all in all,"
which, whatever else it might mean, implies no separation between Him and
the rest of his Creation.
The "Divine Lover" theme, with its implicit promise of consummation,
is also evidence of this ultimate plan. See the Song of Songs interpreted
as God's love for his people, the prophets urging Israel to abandon "adultery"
(idolatry), and return to her true Lover, and Jesus referring to Himself
as the Bridegroom, and His followers as the Bride, throughout the Gospels.
Also, the conclusion of Revelation is the "Wedding Feast" of the Lamb of
God (consummation of the romance between God and Man). Many, many
more examples. Church history develops the theme in Traditional Christian
circles (entirely apart from Gnosticism.)
Most notably, the Carmelite tradition of Sts. John of the Cross and Teresa
of Avila comes readily to mind.
The Divine Family
St Francis of Assisi's famous Canticledevelops the idea of a Divine family. Even the elements of creation
are alive, and not only that, but brothers and sisters to us, children
of one Father. One translation of the modern Franciscan rule of life is
to "protect all life, animate and inanimate"
