At the age of sixteen she had a vision which convinced her of the need to establish a liturgical feast for Corpus Christi "in which believers would be able to adore the Eucharist so as to augment their faith, increase the practice of virtue and mend the wrongs done to the Blessed Sacrament", said the Holy Father.

"It was", Pope Benedict continued his catechesis, "Bishop Robert Thourotte of Liege who, following some initial hesitation, accepted the proposal made by Juliana and her two companions and instituted, for the first time, the Solemnity of Corpus Domini in his diocese. Other bishops later imitated him and established the same feast in the areas under their pastoral care".

"Although following the death of Urban IV the celebration of Corpus Domini was restricted to certain regions of France, Germany, Hungary and northern Italy, in 1317 Pope John XXII reintroduced it for the whole Church".

"Joyfully I wish to affirm that there is a 'Eucharistic springtime' in the Church today", said the Holy Father. "How many people remain in silence before the Tabernacle sustaining a dialogue of love with Jesus! It is consoling to know that many groups of young people have rediscovered the beauty of prayer and adoration before the Blessed Sacrament. I pray that this 'Eucharistic springtime' may become increasingly widespread in parishes, and especially in Belgium, homeland of St, Juliana".

"Recalling St. Juliana of Cornillon, let us too renew our faith in the real presence of Christ in the Eucharist. ... Faithfully encountering the Eucharistic Christ at Sunday Mass is essential for our journey of faith, but let us also seek to visit the Lord frequently, before His presence in the Tabernacle. ... By gazing at Him in adoration the Lord draws us to Him, to His mystery, in order to transform us as He transforms the bread and wine".
