[1] Fernández Solar was a pious child but had an often unpredictable temperament for she could be prone to anger and being vain but could also demonstrate her charitable and loving nature; she seemed transformed when she decided to become a nun and her character seemed to change for her sole ambition was to dedicate herself to the service of God.

Solar was beatified on 3 April 1987 in Chile after a miracle attributed to her from her native land cleared her for beatification while another miracle coming from Chile led Pope John Paul II to canonize her as a saint on 21 March 1993 in Saint Peter's Basilica.

[2] Fernández Solar received her education in a college managed by French nuns from the Sacred Heart order, and she remained there from 1907 until 1918.

In her childhood, she read the autobiographical account that Thérèse of Lisieux had written and the experience had a profound effect on her pious and innocent character while also coming to the realization that she wanted to live for God alone.

Her further inspiration for this self-transformation was her upcoming First Communion which led her to this commitment in an effort to achieve worthiness of what she was soon to receive.

[1] In September 1917 she sent a letter to the prioress of the Discalced Carmelite convent close to her home expressing her desire to enter the order.

On 7 May 1919 she entered the novitiate of the Discalced Carmelites in Los Andes at which time she was given the new religious name of "Teresa of Jesus"; she later received the habit on the following 14 October.

The confirmation of her model life of heroic virtue on 22 March 1986 allowed for Pope John Paul II to title her as Venerable after the C.C.S.

[6] This was done in O'Higgins Park in Chile while her brother Luis was present at her beatification; he was the last direct relative of hers still alive then.

The process for a miracle attributed to her - the definitive one for sainthood - was investigated from 4 December 1990 to 12 June 1991 again in Chile while it received validation not long after on 18 October 1991.

John Paul II confirmed the healing as a miracle on 11 June 1992 while he later canonized her on 21 March 1993 in Saint Peter's Square.

[6][7] Her life was used for a Chilean television miniseries spanning from 6 August until 10 September 1989 starring Paulina Urrutia as Teresa of Jesus.
