The following comes from an April 18 Vatican Information Service blog post:
This morning in the Holy See Press office, the Day of Reflection dedicated to “Friar Junipero Serra, apostle of California, witness of holiness”, to be held on Saturday 2 May at the Pontifical North American College of Rome, Italy. At the beginning of the press conference, Fr. Federico Lombardi, S.J., announced that the Pope will canonise Blessed Junipero Serra on 23 September during his apostolic trip to the United States, outside the National Shrine in Washington, D.C.
The event on 2 May, convoked by the Pontifical North American College and the Pontifical Commission for Latin America, and funded by the archdiocese of Los Angeles, will aim to inform on the life, mission and witness of holiness of Friar Junipero Serra, O.F.M. (1713-1784).
Speakers at the conference were Cardinal Marc Ouellet, P.S.S., president of the Pontifical Council for Latin America; Guzman Carriquiry Lecour, secretary of the vice-presidency of the same dicastery; Fr. Vincenzo Criscuolo, O.F.M. Cap., general rapporteur of the Congregation for the Causes of Saints; and Msgr. James Francis Checcio, rector of the Pontifical North American College.
The activities to take place on the Day of Reflection include the Pope’s visit to the Pontifical North American College, during which he will officiate at Holy Mass.
