[3] In 1878 he then studied Philosophy and Theology for four years at the major seminary in Granada, where he was sponsored and protected by the professor and canon Joaquin Torres Asensio.

Later, as Chaplain of Bernardine nuns in the church of the Sacrament in Almudena parish, he became distinguished by his activity in the suburbs of the capital with the cleaners and "dressmakers".

In 1890 he began to teach Latin literature, pastoral theology and metaphysics at the seminary in Madrid,[2] and was a notary and registrar of the vicariate of the diocese.

During this period he described himself as a "fan of the Jesuits", because since his time as a student of theology at Granada he had wanted to join the Order.

After tertianship in 1910 at Manresa (Barcelona), he was sent to Madrid, where he took final vows at his residence at Calle de la Flor Baja and where lived the rest of his life.

He excelled as a preacher and as a regular confessor, which caused long lines of faithful who were looking for support and spiritual help.

[5] In 1911 the International Eucharistic Congress in Madrid instituted the "Guard of Honor of the Sacred Heart" and entrusted it to Rubio.

[6] He developed his work in towns and suburbs, and founded and organized several associations such as the work of the "Marys of the Tabernacles", and social schools in Ventilla neighborhoods, aided by young teachers Juan and Demetrio de Andrés, known as "Ventilla martyrs" killed during the Civil War, 1936.

During his life miraculous events were reported, such as bilocation, healings, prophecy and clairvoyance, some, perhaps legendary, but others ratified by numerous witnesses.

His remains are venerated in the church of San Francisco de Borja and the Sacred Heart of the Society of Jesus in Madrid.

The extraordinary fact, considered as a miracle by the Congregation for the Causes of Saints in order for his canonization, was the healing of lung cancer of the Jesuit José Luis Gómez Munten (1988).
