"The people of God are essential, pastors are from the people of God and they are also there to serve the people of God," Astaburuaga said, adding that all baptized are called to be "builders of the Church."
The priest said that in order to change the "culture of abuse and concealment" Pope Francis spoke of in a recent letter to Chilean Catholics, a careful process of discernment is needed which takes three things into consideration: time, people and place.
When contemplating any decision, it's important to think about "who are the people, places and times," he said, stressing that the process of renewal in Chile is "the work of everyone, not just one."
"This is why the pope insisted on returning to the concept of the people of God from the Second Vatican Council. We are all responsible: priests, bishops, laity, the holy people. It's a joint task."
Pope Francis, he said, listened "very carefully" when he spoke about his experience accompanying victims of abuse. "This is the testimony he gave us. To listen, and to listen with a lot of attention (and) a lot of trust."
Though the process has at times been difficult, Astaburuaga said accompanying victims such as Cruz and Hamilton over the past 20 years "has its fruits," and "it's a great joy in the midst of their great suffering."
Pope Francis, he said, also asked them to continue praying for the Church in Chile, particularly by emphasizing Eucharistic Adoration more strongly in local dioceses.
The pope also again asked for forgiveness in the name of the Church for the suffering each of them has lived, said Astaburuaga, who called the act "a great humility" on the part of the pope.
"I'll go back to Chile with a lot of hope," he said, adding that "beyond the difficulties there are, conflicts are always an opportunity. Conflicts that we have to face, but always with hope."
Most of those who came to the Vatican for the June 2 meeting with the pope participated in an investigation of abuse cover-up by the hierarchy in Chile, which took place in February and was conducted by Archbishop Charles Scicluna of Malta and Msgr. Jordi Bertomeu of the Congregation for the Doctrine of the Faith. The others worked with the investigation after the archbishop's time in Chile.
This weekend's gathering conclude the pope's first round of meetings with the victims of abuses which occurred at Karadima's Sacred Heart parish in Santiago.

Pope Francis said Mass for the group June 2, after which he met the nine as a group before holding individual conversations. He had met with three more of Karadima's victims, Juan Carlos Cruz, James Hamilton, and Andres Murillo, at the Vatican April 27-30.
Karadima was convicted by the Congregation for the Doctrine of the Faith in 2011 of abusing minors, and sentenced to a life of prayer and penance. He has not been sentenced by civil courts because of Chile's statue of limitations.
A priestly association Karadima was involved in and which he had led for many years, the Priestly Union of the Sacred Heart, was suppressed within a year of his conviction.
Attention to Karadima's abuse has heightened since the appointment of Bishop Juan de la Cruz Barros Madrid to the Diocese of Osorno in 2015. Barros had been accused of both covering up and at times participating in Karadima's abuses.
Pope Francis initially defended Barros, saying he had received no evidence of the bishop's guilt, and called accusations against him "calumny" during a trip to Chile in January. He later relented, and sent Scicluna to investigate the situation in Chile.
After receiving Scicluna's report, Francis apologized, said that he had been seriously mistaken, and asked to meet the country's bishops and more outspoken survivors in person.
