12. This year, when the centenary of the glorious death of Thérèse of the Child Jesus and the Holy Face is being celebrated, as we prepare to celebrate the Great Jubilee of the Year 2000, after receiving a great number of authoritative petitions, especially from many Episcopal Conferences throughout the world, and after accepting the official petition, or Supplex Libellus, addressed to me on 8 March 1997 by the Bishop of Bayeux and Lisieux, as well as from the Superior General of the Discalced Carmelites of the Blessed Virgin Mary of Mount Carmel and from the Postulator General of the same order, I decided to entrust the Congregation for the Causes of Saints, which has competence in this matter, with the special study of the cause for conferring the title of Doctor on this Saint, "after hearing the opinion of the Congregation for the Doctrine of the Faith regarding the eminent doctrine" (Apost. Const. Pastor Bonus, n. 73).

After the necessary documentation had been collected, the two above-mentioned Congregations addressed the question in the meetings of their respective consultors: the Congregation for the Doctrine of the Faith on 5 May 1997, with regard to the "eminent doctrine", and the Congregation for the Causes of Saints on 29 May of the same year, to examine the special "Positio". On the following 17 June, the Cardinals and Bishops who are members of these Congregations, following a procedure approved by me for this occasion, met in a plenary interdicasterial session and discussed the cause, giving a unanimously favourable opinion on granting the title of Doctor of the Universal Church to St Thérèse of the Child Jesus and the Holy Face. I was personally informed of this opinion by Cardinal Joseph Ratzinger, Prefect of the Congregation for the Doctrine of the Faith, and by the Pro-Prefect of the Congregation for the Causes of Saints, Archbishop Alberto Bovone, titular Archbishop of Caesarea in Numidia.

In view of this, on 24 August last, during the Angelus prayer in the presence of hundreds of Bishops and before a vast throng of young people from around the world, gathered in Paris for the 12th World Youth Day, I wanted personally to announce my intention to proclaim Thérèse of the Child Jesus and the Holy Face a Doctor of the Universal Church during the celebration of World Mission Sunday in Rome.

Today, 19 October 1997, in St Peter's Square, filled with faithful from every part of the world, and in the presence of a great many Cardinals, Archbishops and Bishops, during the solemn Eucharistic celebration I proclaimed Thérèse of the Child Jesus and the Holy Face a Doctor of the Universal Church in these words: Fulfilling the wishes of many Brothers in the Episcopate and of a great number of the faithful throughout the world, after consulting the Congregation for the Causes of Saints and hearing the opinion of the Congregation for the Doctrine of the Faith regarding her eminent doctrine, with certain knowledge and after lengthy reflection, with the fullness of Our apostolic authority We declare Saint Thérèse of the Child Jesus and the Holy Face, virgin, to be a Doctor of the Universal Church. In the name of the Father, and of the Son and of the Holy Spirit.

This having been duly enacted, We decree that this Apostolic Letter is to be religiously preserved and to have full effect both now and in the future; furthermore, it is thus to be judged and defined as right, and whatever to the contrary may be attempted by anyone, on whatever authority, knowingly or unknowingly, is null and void.

Given in Rome, at St Peter's, under the Fisherman's ring, the 19th day of the month of October in the year of the Lord 1997, the 20th of the Pontificate.
