Dorothy Day was an admirer of Thérèse (she even named her own daughter Teresa), seeing in her that “however politically or socially involved a person may be, the love that motivates him or her is far more important than exterior accomplishments.”
Thérèse was canonized in 1925. On October 19, 1997, Pope John Paul II proclaimed her a Doctor of the Church, the third woman to be so recognized in light of her holiness and the influence of her teaching on spirituality in the Church.
From Franciscan Media:
Thérèse has much to teach our age of the image, the appearance, the “self.” We have become a dangerously self-conscious people, painfully aware of the need to be fulfilled, yet knowing we are not. Thérèse, like so many saints, sought to serve others, to do something outside herself, to forget herself in quiet acts of love. She is one of the great examples of the gospel paradox that we gain our life by losing it, and that the seed that falls to the ground must die in order to live.
