Burkemper was up next, faced with a preaching scenario that would challenge any 23-year-old priest-to-be. His homily was for a marriage between a Catholic man and a Jewish woman.
As he began, he worked hard on his delivery, as his professor had taught him. "Father Wester is big on delivering the homily," Burkemper said later. "Not just reading it."
The Rev. Donald Wester, pastor of All Saints Catholic Church in St. Peters, Mo., is Kenrick's lecturer of homiletics the art of preaching.
He believes homilies should be practical and direct that they should draw a connection between the everyday struggles of parishioners and biblical truths.
And it's exactly the kind of preaching that U.S. Catholic bishops are hoping for as part of a new national effort to foster better Catholic homilies.
At their annual fall meeting this month, the U.S. Conference of Catholic Bishops voted overwhelmingly to accept the new preaching document, their first since 1982.
The document is an admonishment of poor preaching, saying the bishops are "aware that in survey after survey over the past years, the People of God have called for more powerful and inspiring preaching. A steady diet of tepid or poorly prepared homilies is often cited as a cause for discouragement on the part of laity and even leading some to turn away from the church."
St. Louis Archbishop Robert Carlson had been working on the document for nearly two years, with Wester among his advisers. In an interview, the archbishop said his own father had strong feelings about preaching.
"It's not enough to tell me what the Bible says," Carlson recalled his father saying. "I need to know how to apply what the Bible says about my role as a father, a spouse and a businessman."
The bishops had been discussing the possibility of a preaching document since 2006. But Pope Benedict XVI inspired them to act, issuing two "apostolic exhortations" in the past five years.
In the first of those statements, Benedict wrote in 2007 that "given the importance of the word of God, the quality of homilies needs to be improved."
Then, in a 2010 statement, the pope offered more specifics.
"Generic and abstract homilies which obscure the directness of God's word should be avoided, as well as useless digressions which risk drawing greater attention to the preacher than to the heart of the gospel message."
Carlson, who heads the bishops' Committee on Clergy, Consecrated Life and Vocations, said the bishops expected the new preaching document would be used not only by seminarians, but also by bishops, priests and deacons.
"You can't sit down Saturday evening," Carlson said, "type out a homily and expect to move people's minds and hearts."
The Rev. David Meconi, a theology professor at St. Louis University and editor of the journal Homiletic & Pastoral Review, said the church needed "preachers willing to preach out of their own heart."
"Too many priests read as if they're giving a lecture, and others don't do any preparation and just wing it," Meconi said. "The heart of a good message is pathos, passion."
According to the bishops' new document, and using the Catholic term, "catechize," for teaching the faith, today's preacher "must realize that he is addressing a congregation that is more culturally diverse than previously, one that is profoundly affected by the surrounding secular agenda and, in many instances, inadequately catechized."
Wester said he believes the document does a good job suggesting a balance. On one side is the responsibility of the priest to use his time in front of a captive audience each Sunday to teach, and on the other is the duty to foster a mystical connection between God and his flock.
"If we want people to understand their faith, catechesis has to make sense for them in their own life," Wester said. "Sometimes I want you to know I'm your pastor, an authority. Jesus was not afraid to speak the truth, and then love people."
Carlson said another feature of the new document is the bishops' encouragement of preachers to examine their own faith.
"In this document we ask preachers to also grow themselves spiritually," he said, "so that what they're communicating has powerful meaning in witness of their own life."
At Kenrick on a recent afternoon, Wester had his students spend the first half-hour of class contemplating verses from St. Paul's letter to the Philippians.
One of them read the verses aloud to the rest, and then the 10 young men sat in silence, some reading the text, others with their eyes closed in prayer or thought.
The students repeated the process two more times and, at the end of the half hour, shared with each other how the scripture had moved them.
Wester told the seminarians that after a while in the real world, the temptation to skip the meditation on scripture and move directly on to writing the homily would grow. He urged them to stave off pragmatism for prayer.
That's advice that Burkemper took to heart as he prepared his faux homily for the marriage between a Catholic man and a Jewish woman.
His classmates were impressed with the final product. They thought he did "a great job discussing the covenant relationship in both faiths." They also liked that it was "short, sweet and to the point."
Wester chimed in that it clocked in at five minutes and seven seconds.
"At first you have to get them up there, and let them know they're not going to have a heart attack," Wester said in an interview. "But after they get over the initial fear, it's so neat watching these guys get their legs."
