Bishop Peter Dai Bui believes priests are not just “workers in the vineyard” but “sons and brothers who need to be accompanied,” and this conviction has led to a new role in the Diocese of Phoenix that will help ensure all priests are supported spiritually, physically, and emotionally.
“I believe that a priest who is known, accompanied, and cared for brings that fullness to everything he does: to the altar, to the confessional, to the bedside of the dying,” Bui, auxiliary bishop for the Diocese of Phoenix, told EWTN News.
Father Greg Schlarb, who is currently a pastor at Our Lady of Perpetual Help Parish in Scottsdale, Arizona, will pioneer the role of vicar for priestly life and ministry for the diocese, working with Bui, the vicar for clergy, to care for priests in the diocese.
While Bui’s role is practical — handling priestly assignments and personnel management — Schlarb will take a “more proactive and personal approach,” according to the diocese.
“I want to be a sounding board, a listening ear, and a compassionate brother who is there to support and assist them,” Schlarb told EWTN News.
No priest has to walk alone
“Priestly formation does not end at ordination,” Bui said. “It is a lifelong journey, and every priest needs someone walking alongside him in that journey. Father Schlarbʼs role exists to make sure no priest in the Diocese of Phoenix has to walk it alone.”
“When our priests are well — humanly, spiritually, pastorally — their people feel it,” Bui continued.
The new role is one of several mental health efforts established by Bishop John Dolan of Phoenix. Dolan, who has lost four family members to suicide, is known for his mental health advocacy.
“Bishop Dolan has always understood that the health of the diocese depends on the health of its priests, and as that conviction deepened, it became clear that priestly life and ministry deserved its own dedicated focus, that is, as a distinct and primary pastoral priority,” Bui said.

“How do we make sure our priests have what they need, that they are healthy: spiritually, physically, mentally; that they constantly are formed and transformed in their relationship with Christ?” Dolan asked in his monthly podcast, “Tilma,” which highlighted the new role.
“Youʼre not just ordained a priest, but youʼre ordained a priest in the presbyterate — that means there’s a community of priests of which you belong,” Dolan said.
The Diocese of Phoenix spans 44,000 square miles and is the fastest-growing diocese in the U.S. It is home to more than 2 million Catholics and 94 parishes.
“It’s my hope that all of our priests, no matter how far away they are from the Phoenix metropolitan area, will feel supported, heard, and loved,” Schlarb said.
“Just as the parishioners they serve understand that the presence of a priest shepherding in the farthest parts of our diocese demonstrates the care, concern, and love of our bishop, so these heroic priests who serve in these remote parishes will also experience that same care, concern, and love through the presence and support I am able to offer them,” Schlarb said.
A pastor’s heart
“Priests can often face challenges when their life is ‘out of balance,’” Schlarb said. “Sometimes there are personnel issues that cause great concern, or ‘actively disengaged’ parishioners are placing stumbling blocks for our pastors, or there’s little to no opportunity to create community in these remote areas.”
But Bui said he believes Schlarb has “exactly the right gifts to this work.”
“He has a pastorʼs heart, a brother priestʼs credibility, and a genuine love for his fellow priests,” he said.
Even though he does not start in the role until July 1, Schlarb said priests have already begun to reach out.
“There have been priests reaching out for guidance with pastoral challenges, new assignment excitement, and concerns and guidance on applying for sabbaticals or ongoing formation opportunities,” Schlarb said.
“I am grateful to God for this assignment that Bishop John Dolan has entrusted to me and with the guidance of the word or God and the Holy Spirit, I hope to serve our priests to the best of my ability,” he said.
