I was curious to find out more about Father Dan, and when I googled him for older stories thought it strange that the Nashville diocese website had changed the urls on these two stories so that they were "404 NOT FOUND"

Father Daniel Reehil celebrates his first Mass Sunday, July 27, 5 p.m., Cathedral, Nashville. He is assigned as Associate Pastor of St. Edward Church, Nashville with part-time duties at the Catholic Center.
 
A pilgrimage to Medjugorie, where a group of teens said they were visited by the Virgin Mary, changed the course of Deacon Daniel Reehil’s life.
 
He quit his job on Wall Street, delved deeply into his Catholic faith, began to discern a call to the priesthood, and ended up in Nebraska as a brother with the Intercessors of the Lamb community, leading retreats and parish missions.
 
When problems with the community led to the local bishop suppressing the group, Deacon Reehil decided to follow a call he had felt to the priesthood. Eventually, he came to Middle Tennessee, and on Saturday, July 26, he will be one of nine men who are ordained as priests for the Diocese of Nashville.
 
“I love Nashville. I love Bishop (David) Choby,” said Deacon Reehil, who was ordained as a transitional deacon last April.
 
It’s taken him 12 years to get to this point in his life, he said, but it’s the right place. “This is where I’m supposed to be. … Getting to where you need to be can be difficult, but in hindsight it’s clear this is where you’ve been heading all along.”
 
Deacon Reehil grew up in a Catholic family in Long Island, N.Y. After graduating from the University of Dayton, he returned to New York and started a career in the business world.
 
In 1997, he made a pilgrimage to Medjugorje. “It changed my life,” he said. While there, he went to confession for the first time in 20 years, and the priest who heard his confession said, “I think you have a calling to be a priest.”
 
When he returned to New York, he started taking his faith more seriously. He found a spiritual director and began praying regularly.
 
“I felt God was calling me to do something different but I didn’t know what,” Deacon Reehil said. One Sunday, after receiving Communion, he felt a call to follow God. “I called in sick on Monday and resigned on Tuesday.”
 
His life took another turn with the 9/11 attacks. Several of his friends who worked at the World Trade Center were killed in the attack. While attending a healing Mass, he met Father Tom DiLorenzo, a Boston priest who is involved in the Charismatic movement and has a Catholic radio and television program.
 
Father DiLorenzo asked him what he was doing with his life. When he answered nothing, he said, “Maybe you need to be in Boston.”
 
“I went there for the weekend and stayed nine months,” Deacon Reehil said. Father DiLorenzo became a mentor. “He lived the gospel.”
 
Eventually, Reehil became a seminarian for his home diocese of Rockville Centre on Long Island. But while attending a silent retreat with the Intercessors of the Lamb in Nebraska, “I thought I was being called to that community.”
 
Deacon Reehil, as a brother, helped lead retreats at the Intercessors’ motherhouse and in parishes. “People from all over the world looking for discernment or healing would come to the Intercessors,” he said. “You can really see people’s lives changed.”
 
Though no longer part of the community, Deacon Reehil is still animated by its ministry of intercessory prayer and offering people’s suffering to Christ for the benefit of others.
 
“Suffering can be a great moment of power to help other people,” Deacon Reehil said. “When people realize they have that power to unite their suffering to the Cross … Jesus is born in hearts again.”
 
When he left the Intercessors, Deacon Reehil returned to Holy Apostles Seminary in Cromwell, Conn., and completed his studies last year.....

the clue here is this

he met Father Tom DiLorenzo, a Boston priest who is involved in the Charismatic movement and has a Catholic radio and television program.

"Charismatic" that is basically Pentecostal-izing. Not exactly a Catholic theological thing, but certainly more like a Tennessee thing. Soon Father Dan might have the children handling snakes and such to cast out the demons...

In one way, I guess this is not anathema to the Catholic Church, because their general modus operandi over the ages has been to try to adapt to tribal customs and practices of the local indigeneous peoples.
