Happy feast day of St. Thomas Aquinas, particularly to all Dominicans, but also to all who hold to the Catholic faith! St. Thomas is indisputably one of the most important saints in the history of the Church. He is well-known for his Summa Theologiae and his many other theological works, but we often benefit from his contributions to the Church's Eucharistic devotions, perhaps without even knowing it.
St. Thomas Aquinas composed the liturgy for the feast of Corpus Christi, and included in it the Pange Lingua, which he also wrote and which we hear every Holy Thursday. Aquinas also wrote the hymns Panis Angelicus, O Salutaris Hostia, and Adoro Te Devote. I have embedded them below for you (they are also in my playlist at the bottom of the page. Translations of the Latin may be found here.
Enjoy! St. Thomas Aquinas, ora pro nobis!
O Salutaris Hostia (5th and 6th verses of Verbum Supernum)
