In the eleventh century, a French archdeacon challenged the Church’s faith that the Blessed Sacrament was in fact the Body and Blood of Christ. Pope Gregory VII (reigned 1073–85) responded with a definitive statement of what the Church had always believed. After the controversy was resolved, Eucharistic adoration began to flourish. The Church soon instituted processions of the Blessed Sacrament, prescribed rules for Eucharistic adoration, and encouraged the faithful to visit Our Lord reserved in the churches. The martyr St. Thomas à Becket (1118–70), for example, once wrote to a friend that he often prayed for him in the church before “the Majesty of the Body of Christ.” In 1226, after King Louis VII of France (1120–80) won a victory over the Albigensian heretics who had taken up arms against him, he asked the Bishop of Avignon to have the Blessed Sacrament exposed for adoration in the Chapel of the Holy Cross. The faithful who came to adore were so numerous that the bishop allowed the adoration to continue indefinitely, day and night. This decision was later ratified by the pope, and adoration at Avignon continued uninterrupted until 1792, when the French Revolution halted the devotion. It was resumed, however, in 1829. Also in the thirteenth century, Pope Urban the IV (reigned 1261–64) instituted the Feast of Corpus Christi (the Body of Christ), commissioning St. Thomas Aquinas to write hymns for the feast. The lyrics for these compositions reflect a profound awareness of Christ’s abiding Presence with us in the Blessed Sacrament and of the reverence, adoration, and gratitude we owe Him for that surpassing Gift.
