St. Therese wrote "My Weapons" for the profession of her cousin, Marie Guerin, Sister Marie of the Eucharist. Marie was the last of Therese's five novices to enter and thus the last to profess her vows (on March 25, 1897).  Therese had only a little more than six months to live when she wrote:

Smiling, I bravely face the fire.

And in your arms, O my Divine Spouse,

I shall die singing on the battlefield,

My Weapons in hand!...
