Gomez shared an open letter to the members of the archdiocese, informing them of the settlement and apologizing for the actions of past clergy members. "I am sorry for every one of these incidents, from the bottom of my heart," Gomez wrote, in part. "My hope is that this settlement will provide some measure of healing for what these men and women have suffered." Archbishop José H.

Stewart, an attorney for the victims. “I encourage other religious institutions within the Catholic Church to meet their responsibilities and take accountability.”
