Miguel Lluch studied Geography and History at the University of Alicante and received his PhD in Theology at the University of Navarra (1988). Later, at the Catholic University of Louvain he obtained the Diploma of the high school of programs of study Medieval (1991), as well as a second doctorate in "Histoire de la civilisation médiévale" (1994). He has been a professor at the School of Theology at the University of Navarra for almost thirty years.

He was ordained a priest on August 15, 1987, incardinated in the Prelature of Opus Dei. He dedicated his best efforts to pastoral work, especially as a university chaplain. Everyone remembers him as an endearing person, to whom many turned for guidance and spiritual guidance financial aid .

He developed his research in theology under the direction of Professor Josep-Ignasi Saranyana. In 1990 he published his first doctoral thesis on "The Theology of Severinus Boethius", also translated into Italian. The second thesis , "The scholastic treatise on the Decalogue", was published in Louvain. These were followed by other works in specialized publications.

Between 1998 and 2010 his dedication to the University of Navarra was linked to the high school of Anthropology and Ethics, which he directed since 2001. The high school was set up with a mission statement as ambitious as it was necessary: to contribute to the Christian intellectual training of students and professors in an increasingly secularized society. The aim was not to establish a confrontation between faith and reason or between Christianity and modernity, but, on the contrary, to build bridges of dialogue and show the intellectual vigor of Christian modernity. Miguel Lluch dedicated his best years to this task. Due to the novelty of approach in our cultural context, there was no lack of challenges and difficulties, which his good humor and indefatigable determination made more bearable. From high school he promoted numerous symposiums, interdisciplinary seminars and publications, with the participation of some of the most outstanding names of the international cultural discussion .

Among his intellectual references was Romano Guardini, another great priest and university professor. With him, he set out to achieve what John Paul II had been asking for in his magisterium: that faith become culture. The idea was to propose a Christian vision of the world. subject As Miguel Lluch explained, "Catholicism is not a special way of being or living (...) but a determined attitude", the attitude of considering the world from Christ. The university has an irreplaceable contribution to make in this task: to show from the different sciences and knowledge the divine relief of human realities. St. Josemaría Escrivá, whom Miguel Lluch had as his life model , had already formulated it when he proposed a "Christian materialism".
In spite of his premature and unexpected departure, we are left with the certainty that he can now contemplate our reality in all its relief.
