WContra errores Graecorum, ad Urbanum IV Pontificem Maximum is a short treatise written in 1263 by Roman Catholic theologian Saint Thomas Aquinas as a contribution to Pope Urban's efforts at reunion with the Eastern Church. Aquinas wrote the treatise in 1263 while he was papal theologian and conventual lector in the Dominican studium at Orvieto after his first regency as professor of theology at the University of Paris which ended in 1259 and before he took up his duties in 1265 reforming the Dominican studium at Santa Sabina, the forerunner of the Pontifical University of Saint Thomas Aquinas, Angelicum, in Rome.
W"Lauda Sion" is a sequence prescribed for the Roman Catholic Mass for the feast of Corpus Christi. It was written by St. Thomas Aquinas around 1264, at the request of Pope Urban IV for the new Mass of this feast, along with Pange lingua, Sacris solemniis, Adoro te devote and Verbum supernum prodiens, which are used in the Divine Office.

WThe Quinque viæ are five logical arguments for the existence of God summarized by the 13th-century Catholic philosopher and theologian St. Thomas Aquinas in his book Summa Theologica. They are:the argument from "first mover"; the argument from causation; the argument from contingency; the argument from degree; the argument from final cause or ends.
W"Sacris solemniis" is a hymn written by St. Thomas Aquinas (1225–1274) for the feast of Corpus Christi. The strophe of Sacris solemniis that begins with the words "Panis angelicus" has often been set to music separately from the rest of the hymn. Most famously, in 1872 César Franck set this strophe for voice (tenor), harp, cello, and organ, and incorporated it into his Messe à trois voix Opus 12. The hymn expresses the doctrine that the bread and wine are changed into the Body and Blood of Christ. In the Roman Catholic tradition the concept of transubstantiation is presented as an explanation of how this change happens.
