Saint Thomas Aquinas, O.P., also Thomas of Aquin or Aquino; (Aquino, 1225 – Fossanova, 7 March 1274) was an Italian priest of the Catholic Church in the Dominican Order, and an immensely influential philosopher and theologian in the tradition of scholasticism, known as Doctor Angelicus (the Angelic Doctor) and Doctor Communis or Doctor Universalis (the Common or Universal Doctor). He is frequently referred to as Thomas because "Aquinas" refers to his residence rather than his surname. He was the foremost classical proponent of natural theology, and the father of the Thomistic school of philosophy and theology. His influence on Western thought is considerable, and much of modern philosophy was conceived as a reaction against, or as an agreement with, his ideas, particularly in the areas of ethics, natural law and political theory.
Aquinas is held in the Catholic Church to be the model teacher for those studying for the priesthood. The works for which he is best-known are the Summa Theologica and the Summa Contra Gentiles. One of the 33 Doctors of the Church, he is considered the Church's greatest theologian and philosopher. Pope Benedict XV declared: "The Church has declared Thomas' doctrine to be her own."
Thee we adore, O hidden Savior, Thee,
Who in Thy sacrament dost deign to be;
Both flesh and spirit at Thy presence fail,
...
Sing, my tongue, the Saviour's glory,
Of His cross the mystery sing;
Lift on high the wondrous trophy,
Tell the triumph of the King:
...
The heavenly Word proceeding forth,
Yet leaving not the Father’s side,
Accomplishing His work on earth
Had reached at length life’s eventide.
...
Zion, to Thy Savior singing,
To thy Prince and Shepherd bringing,
Sweetest hymns of love and praise,
Thou wilt never reach the measure
...
O saving Victim, open wide
The gate of Heaven to man below;
Our foes press on from every side;
Your aid supply; Your strength bestow.
