Don Justo dedicated the building to Our Lady of the Pillar (Spanish: Nuestra Señora del Pilar).

[4] At the age of ten he witnessed communist forces, who were fighting Francisco Franco, shooting priests and ransacking the church in Mejorada del Campo; the events left him with little respect for the town's socialist administration.

In 1961, he had to leave prior to making his final vows, when he contracted tuberculosis and his health deteriorated because of the ascetic way of life of the Trappists.

[6] Justo had promised that if he recovered from the tuberculosis which had struck him down, he would build a shrine in honour of Our Lady of the Pillar, to whom he had prayed.

Design inspirations have included St. Peter's Basilica in the Vatican City, the White House in the US, and various castles and churches in Spain.

Eusebio Sanchez Dominges, the parish priest, described Justo as a devout man who attended Mass every Sunday.

According to local media, shortly before his death, Don Justo bequeathed his enormous building to the non-governmental organization Messengers of Peace (Spanish: Mensajeros de la Paz), which committed itself to completing his life's work.

The town authorities, however, have named the street on which the project has been rising "Calle Antonio Gaudí", after the architect behind another famous unfinished church, the Sagrada Familia.

With strokes of surrealism, the story dives into the psyche of these two ambivalent characters that make up the bizarre microcosm of the “Cathedral of Faith”.
