The Legacy of St. Thomas Aquinas

St. Thomas Aquinas is the patron saint of higher education, scholars, theologians, and Catholic schools. His tremendous impact lives on through the many roles he fulfilled: priest, philosopher, theologian, legal expert, and political scientist.

Today, STA is a Catholic high school that serves as a representation of St. Thomas Aquinas’ legacy in education. Our learning environment challenges students and provides some of the most unique and transformative experiences in New England.

Lux in Tenebris

LIGHT IN DARKNESS

In Latin, Lux in Tenebris means Light in Darkness. St. Thomas Aquinas believed that God is the source of the light of natural reason and faith. This phrase is the cornerstone of everything we do in STA — we are a school born of vision, defined by Catholic character, and intent on enlightening young minds so that they can be the change we wish to see in the world.
