Every now and then, a typical Catholic asks Father Dwight Longenecker for his take on whether Rome will ever ordain more married men as priests. 

This is logical, since Longenecker is a former Anglican priest who is married and has four children. He was raised as a fundamentalist Protestant, graduating from Bob Jones University in Greenville, S.C., and now leads Our Lady of the Rosary Catholic Church in that same city.

These conversations begin with the layperson cheering for married priests. Then Longenecker mentions the "elephant in the room" -- the 1968 papal encyclical Humanae Vitae defending church doctrines forbidding artificial contraception. Surely bishops would strive to ordain men who, with their wives, would defend these teachings. Right?

"They might have a dozen kids," says Longenecker. "Who's going to pay for them?"

The typical Catholic assumes the bishop will do that. Actually, parishes are responsible for their priest's pay, even when his children go to Catholic schools and off to college. That might require parishioners to put more than $5 in offering plates.

The typical Catholic then says: "I don't think having married priests is such a good idea."

Longenecker is ready for more chats -- in person and at his "Standing on my Head" website -- after recent Pope Francis remarks to the German newsweekly Die Zeit.

Asked about the global shortage of priests, Francis expressed a willingness to consider ordaining "viri probati" (tested men), such as married men already ordained as deacons. While "voluntary celibacy is not a solution," he added: "We need to consider if viri probati could be a possibility. … We would need to determine what duties they could undertake, for example, in remote communities."

This latest Pope Francis sound bite was not surprising, since Vatican officials have often discussed ordaining more married men, said Longenecker, author of 15 books on Catholic faith and apologetics.
