He had spiritual experiences and revelations about the Sacred Heart of Jesus that led him to spread this devotion and worship.

In late April 1733 he received a letter from his friend Augustine Cadaveraz (in Bilbao) after he had requested the priest to translate a Latin chapter on Corpus Christi from Joseph de Gallifet's book "On Devotion to the Sacred Heart of Jesus".

[3] On 3 May 1733 he took the book from the library of the house and took it to his room where he began to read it; the Sacred Heart both inspired and illuminated him.

[3][5] He distributed leaflets for the devotion and even wrote a letter to King Philip V asking for his support in requesting the Holy See to approve a special feast for the Sacred Heart.

The formal introduction to the cause came on 11 February 1914 under Pope Pius X and the late Jesuit priest was made a Servant of God.

Pope John Paul II named him as Venerable on 12 January 1996 after confirming that the late Jesuit priest had lived a life of heroic virtue.

Pope Benedict XVI approved this on 17 January 2009 and delegated Archbishop Angelo Amato to preside over the beatification in Spain on 18 April 2010.
