Forks clink on plates in the basement conference room as Guest opens the November meeting in prayer. "In the name of the Father, Son and Holy Spirit," he says as he bows his head and clasps his hands.
Guest is not a visiting professor. He is a seminarian, just like the other younger men at the table.
But he is not alone in his age group. According to a decade-long study of enrollment by the Association of Theological Schools released in 2009, the fastest-growing group of seminarians include those older than 50. In 1995, baby boomers made up 12% of seminarians, while today they are 20%.
"I think I was always looking for something else in a lot of ways and always felt the call to do something else," Guest said.
He spent time in government and Pennsylvania politics before settling into a career in law. He had a three-bedroom home near the Jersey Shore with a meaningful job as an attorney helping the poor.
Though successful by any measure with a job that made a difference, he kept looking.
"Helping people with domestic violence, you know suffering from domestic violence or immigrants who were being deported ... I just saw their brokenness. In so many different ways, they were broken. And I know they needed to be touched by the love of God," he said.
The feeling that something was missing led Guest to Theological College to study to become a parish priest in Camden, New Jersey.

"Ministry, whether that be a priest or a minister or a rabbinical student touches people's lives at the core, where God is where it's most meaningful. I think people grasp that and are searching for that," he said.
Guest, who never married, was good candidate to become a priest. As a young man, he enrolled in the seminary for a few years to become a priest before leaving to experience life.
It is a journey that has played out similarly for a lot of baby boomers.
"Many of them felt a call early in life, maybe in their teenage years or college, and set that aside to be the bread winner for the family or do what the family expected them to do," said the Rev. Chip Aldridge, admissions director at Wesley Theological Seminary in Washington.
The Methodist seminary, which boasts students from 40 denominations, has also seen a rise in baby boomers in the last decade, making for some interesting classes.
For many of the boomers who went to college in the analog age, they have to get up to speed in a hurry to learn in the digital era.
"Everyone has to be able to use online academic tools. ... They've got to be very comfortable with technology," Aldridge said.
The majority of seminarians are still in their 20s and 30s.
