My nature and his active nature are united in one 

person. Not in the person of the Word of God, but in 

the person of the man at prayer. And so what took place 

in Christ, through the virginity of the Most Holy 

Theotokos, when two natures were united in one person, 

in the hypostasis of the Divine Word, now takes place 

in me, through my virginal soul, in travail night and 

day, and finally giving birth, so that the two shall be 

"one flesh" (Gen 2:24), "one spirit" (I Cor 6:17), 

so that becoming one spirit, we will become one man.
