Thomas Aquinas contributed substantially to the bull, mostly in parts concerned with the liturgical text of the new feast. Thomas composed the sequence Tantum ergo sacramentum for this purpose. The successors of Urban IV did not uphold the decree, and the feast was suspended until 1311, when it was reintroduced by Clement V at the Council of Vienne.
