The
Franciscan archives credit Saint
Francis of Assisi (who died in 1226) for starting Eucharistic Adoration in Italy. This process then spread from
Umbria to other parts of Italy by the Franciscans.
[29][30] Francis had a deep devotion to the Eucharist and Saint
Bonaventure commented that Francis would be swept in ecstasy after receiving Communion. For Francis the adoration of the Eucharist amounted to “seeing Christ”.
[31]
The theological basis for the adoration was prepared in the 11th century by
Pope Gregory VII, who was instrumental in affirming the tenet that Christ is present in the Blessed Host; In 1965 the confession of belief that Gregory imposed on
Berengarius was quoted in Pope Paul VI’s historic encyclical
Mysterium Fidei:
[4] “I believe in my heart and openly profess that the bread and wine that are placed on the altar are, through the mystery of the sacred prayer and the words of the Redeemer, substantially changed into the true and proper and lifegiving flesh and blood of Jesus Christ our Lord, and that after the consecration they are the true body of Christ”
[32]
This profession of faith began a “Eucharistic Renaissance” in the churches of Europe.
[4] As of the eleventh century in the
Western Church devotions began to focus on the Eucharistic gifts as the objective presence of the risen Christ and the Host began to be elevated during the liturgy for the purpose of adoration.
[4]
The lay practice of adoration formally began in
Avignon,
France on September 11, 1226. To celebrate and give thanks for the victory over the
Albigensians in the later battles of the
Albigensian Crusade,
King Louis VIII asked that the sacrament be placed on display at the Chapel of the Holy Cross.
[33] The overwhelming number of adorers brought the local
bishop, Pierre de Corbie, to suggest that the exposition be continued indefinitely. With the permission of
Pope Honorius III, the idea was ratified and the adoration continued there practically uninterrupted until the chaos of the
French Revolution halted it from 1792.
In the
thirteenth century the
Feast of Corpus Christi was instituted. From this point devotion to the Blessed Sacrament, both within and outside the Mass, became central in the piety of Western Christians.
