"The Incarnation" by St. John of the Cross

Then he called 

the archangel Gabriel 

and sent him to 

the virgin Mary,  

at whose consent 

the mystery was wrought, 

in whom the Trinity  

clothed the Word with flesh, 

and though Three work this, 

it is wrought in the One; 

and the Word lived incarnate 

in the womb of Mary. 

And he who had only a Father 

now had a Mother too, 

but she was not like others 

who conceive by man. 

From her own flesh 

he received his flesh, 

so he is called 

Son of God and of man.

~St. John of the Cross, "The Incarnation"
