Ignacio Ellacuría was a Jesuit priest, philosopher, and theologian who did important work as a professor and rector at the Universidad Centroamericana "José Simeón Cañas" (UCA), a Jesuit university in El Salvador founded in 1965. Ignacio Ellacuría was a close friend and colleague of the scholars Ignacio Martín-Baró and Segundo Montes, all of whom were assassinated with Ellacuría by the Salvadoran army, along with three colleagues and two employees. His work was defining for the shape UCA took in its first years of existence and the years to come. Ellacuría was also responsible for the development of formation programs for priests in the Jesuit Central American province.
Ellacuría's academic work was an important contribution to "Liberation Philosophy". This school of philosophy stems from the work of Augusto Salazar Bondy and Leopoldo Zea. It focuses on liberating the oppressed in order "to reach the fullness of humanity". Ellacuría was also a strong supporter and contributor to Liberation Theology.
Ellacuria writes in a profound way about how liberation of the oppressed is at the heart of Christianity and the role of the church in bringing this about as the key component of salvation, an ongoing event that takes place in history, not at the end of time or in the next life.
