ROME — Ten years after Benedict XVI broadened access to the celebration of the Traditional Latin Mass, the document by which he did so is being hailed as a means of closing the rift of division following liturgical changes made after the Second Vatican Council.

“Sometimes there are these polemics, but I think Benedict tried to overcome these polemics, saying that even in the liturgy there is a certain progress … but clearly in full continuity with the tradition of the Church,” Father Vincenzo Nuara, OP, told Catholic News Agency May 31.

Tensions were heightened after the Second Vatican Council’s reforms, and “unfortunately these situations of contrast, of opposition are created” even today, Nuara said.

In light of this situation, Benedict XVI’s 2007 motu proprio Summorum Pontificum, which widened access to the pre-Vatican II liturgy, “was not an instrument to divide” or throw further fuel on the flames, he said.

Rather, “it was an instrument to unite. To unite, and to bring again that ecclesial peace that’s needed in this time.

“I see it as a positive instrument, not negative,” Nuara said. “It’s not an instrument for going backwards. It’s an instrument to reconnect ourselves in continuity” with different ecclesial styles.

Nuara is president of the association “Priestly Friends of Summorum Pontificum” and founder and spiritual assistant of the “Youth and Tradition” association.

He is also one of the organizers of an upcoming Sept. 14-17 pilgrimage marking the 10th anniversary of Summorum Pontificum, and spoke to journalists at a working breakfast on the event.

The motu proprio was issued July 7, 2007, and went into effect September 14 of that year, the feast of the Exaltation of the Cross.

The document established that the post-Vatican II Roman Missal, first issued by Blessed Paul VI, is the ordinary form of the Roman rite, and that the prior version, last issued by St. John XXIII in 1962 and known as the Traditional Latin Mass or the Tridentine Mass, is the Roman rite’s extraordinary form.

In the motu proprio, Benedict noted that the Traditional Latin Mass was never abrogated. He awknowledged clearly the right of all priests of the Roman rite to say Mass using the Roman Missal of 1962, and established that parish priests should be willing to say the extraordinary form for groups of the faithful who request it.

Benedict also established that the faithful could have recourse to their bishop or even the Vatican if their requests for celebration of the extraordinary form were not satisfied.

The provisions of Summorum Pontificum for the use of the extraordinary form replaced those of St. John Paul II laid down in Quattuor abhinc annos and Ecclesia Dei.

According to that indult, priests and faithful who wished to celebrate the Traditional Latin Mass had to get permission from their bishop to do so. It could only be for those who requested it, could not normally be said at parish churches, and the bishop could set days and conditions for its celebration.

After the Second Vatican Council, the Missal issued by Bl. Paul VI, also known as the Novus Ordo, was widely adopted. It was widely translated into vernacular languages, and is often celebrated with the priest facing toward the congregation.

However, not a few faithful continued to be attached to the earlier form of the liturgy, and Benedict’s motu proprio was considered a generous response to these faithful.

Benedict wrote in the motu proprio that the two forms “will in no way lead to a division” in the Church’s belief “for they are two usages of the one Roman rite.”

In his letter to bishops accompanying Summorum Pontificum, Benedict also noted that “the two Forms of the usage of the Roman Rite can be mutually enriching.”

Nuara reflected that since Summorum Pontificum, “those who have permission to use the ancient form of the liturgy have also at the same time rediscovered the sanctity of the new.”

This mutual enrichment is a discovery Nuara said he himself has made in his 25 years as a priest, during which he has celebrated both the new and ancient liturgical formulas.

But it is also a discovery “that many (other) priests have made.

“Benedict is a positive man. Benedict, who reflects as a theologian and a pastor, realized that the ancient form that has grown in the history of the Church for years, can give new impetus to the new form,” he said.

The Mass “is the bridge where they meet, because the Eucharist is the point of encounter …  the sacrament of unity,” Nuara said, adding that what “must be avoided” is that people “take advantage of their particular trend or attention to one or the other liturgy, to create fences of division and separation.”

Benedict himself celebrated the new form of the liturgy “with great dignity,” but before his election as Bishop of Rome was also known to celebrate the ancient liturgy with the same esteem.

What Summorum Pontificum seeks to do then, is to work for this unity, he said, adding that at 10 years since its publication, his hope is that people from both sides will work toward this goal.

“We want to send, to communicate this message,” he said. “Because the Church is a family, the family of God.”

When the Summorum Pontificum Pilgrimage takes place in September, it will be a privileged time to show this unity, he said.

The event’s first day, held at the Pontifical University of St. Thomas Aquinas, will feature keynote addresses from Archbishop Guido Pozzo, secretary of the Pontifical Commission Ecclesia Dei; Cardinal Gerhard Müller, prefect of the Congregation for the Doctrine of the Faith and president of the PCED;  and Cardinal Robert Sarah, prefect of the Congregation for Divine Worship.

Pilgrims who come will participate in various other activities throughout the rest of the three days, including adoration and a Eucharistic procession presided over by Archbishop Pozzo on September 16, followed by a Pontifical High Mass said by Cardinal Carlo Caffarra, Archbishop Emeritus of Bologna.

Titled “Summorum Pontificum: A renewed youth for the Church,” the pilgrimage is being organized by the “Priestly Friends of Summorum Pontificum” and “Youth and Tradition” associations in partnership with the Coetus Internationalis Summorum Pontificum.

Speaking of the title in comments to journalists, Nuara noted that a “truly surprising” phenomenon is that the “true protagonists” of this new “season of the Church … are the youth.”

In his letter accompanying the motu proprio, Benedict had noted that while “it has clearly been demonstrated that young persons too have discovered this liturgical form, felt its attraction and found in it a form of encounter with the Mystery of the Most Holy Eucharist, particularly suited to them.”

“Benedict XVI already in 2007 was aware that the new recipients of this liturgy, loved, desired and also sought, were the youth,” Nuara said.

Pope Francis has also commented on the fact that many of the enthusiasts for the Traditional Latin Mass are young people who never knew it growing up, but encountered it later.

“Youth can’t be nostalgic for something they didn’t know,” Nuara said, adding that “this is very nice, because by experience I can say that the youth who draw near to the ancient liturgy of the Church love it” for the reverence and silence of the celebration.

In celebrating the ancient form, “you really understand who is at the center, who the protagonist is,” the priest said, noting that “youth understand very well that this liturgy speaks of … the essential truth of the faith.”
