Pope Benedict recently addressed priests of Rome brought together in the Basilica of St. John Lateran for an ecclesial convention on 15 June.
The Holy Father develops some themes that I have been working with and bashing you with over your heads for years.
The Holy Mass, celebrated in the respect of the liturgical norms and with a fitting appreciation of the richness of the signs and gestures, fosters and promotes the growth of Eucharistic faith. In the Eucharistic celebration we do not invent something, but we enter into a reality that precedes us, more than that, which embraces heaven and earth and, hence, also the past, the future and the present.
This universal openness, this encounter with all the sons and daughters of God is the grandeur of the Eucharist: we go to meet the reality of God present in the body and blood of the Risen One among us. Hence, the liturgical prescriptions dictated by the Church are not external things, but express concretely this reality of the revelation of the body and blood of Christ and thus the prayer reveals the faith according to the ancient principle "lex orandi – lex credendi."
And because of this we can say "the best catechesis on the Eucharist is the Eucharist itself well celebrated" (Benedict XVI, Post-Synodal Apostolic Exhortation "Sacramentum Caritatis," No. 64).
It is necessary that in the liturgy the transcendent dimension emerge with clarity, that of the mystery, of the encounter with the Divine, which also illumines and elevates the "horizontal," that is the bond of communion and of solidarity that exists between all those who belong to the Church.
In fact, when the latter prevails, the beauty, profundity and importance of the mystery celebrated is fully understood. Dear brothers in the priesthood, to you the bishop has entrusted, on the day of your priestly Ordination, the task to preside over the Eucharist. Always have at heart the exercise of this mission: celebrate the divine mysteries with intense interior participation, so that the men and women of our City can be sanctified, put into contact with God, absolute truth and eternal love.
