"Saint Teresa's writings contain a power rather heavenly than human,which is marvellously efficacious in reforming men's lives, so that her books can be read with benefit,
not only by those engaged in the direction of souls,
or by those who aspire to eminent sanctity of life,
but also by everyone who takes any serious interest
in the duties and virtues of a Christian — that is to say,
in the salvation of his own soul."

 From The Address By His Holiness Pope Leo XIII. To The Rev. Marcel Bouix, S.J., March 17, 1883.

Poem 35. SONNET TO JESUS CRUCIFIED.

No me mueve, mi Dios, para quererte.

I am not moved, my God, to love of Thee

Because Thou pledgest heaven in reward, 

Nor is my soul by fear of death so awed 

As to be moved straightway from sin to flee.

        Thou mov'st my love, my God ! to see Thee hang 

Nailed to the cross, of men the scoff, the scorn, Doth move my love ! 

Thy body scourged and torn, Thy mocking and affronts, Thy dying pang ! 

It is Thy love that moves me in such way 

That did no heaven exist, I'd love Thee still ! 

Dread of offence would still my spirit sway 

Were there no hell — Thy gifts move not my will, 

For though I hoped no guerdon in repay,

      The same unaltered love my heart would fill !
