The racier, the better, these Catholics say.
That's what gets the biggest turnouts at their Theology on Tap meetings, where people in their 20s and 30s gather in local bars to talk about everyday issues -- such as condoms or porn.
The Dec. 10 topic: Natural family planning, or "NFP," led by physician Maria Bajoyo.
"We live in a contraceptive culture," she told the crowd of 60 to 70 at Vito's on Penn. "Contraception is anti-children. I really can't think of another example where we take a perfectly healthy bodily system and remove it. Contraceptive sex is sterile by nature. It facilitates premarital sex."
"NFP" was the final part in a six-session series on "Theology of the Body," which also included weekly talks led by experts on sex, marriage and porn. The sessions have grown so much, Theology on Tap organizers have had to change locations several times before landing at Vito's.
Meeting in a relaxed environment like a bar "lets people let their guard down, to feel more comfortable," said Anthony Campo, Theology on Tap director.
The group began in a Chicago suburb in the early '80s, and other cities caught on. The program started in Indianapolis in 2002, and now a group of about 70 -- sometimes more -- meets every other week.
"Talking about controversial topics like contraception brings the crowd in," said Roger Neal, 27, a Theology on Tap organizer.
Not much debate, though, occurred at the Dec. 10 session, where Bajoyo called the pill "intrinsically evil" and urged her audience to look at all their natural options when trying to avoid getting pregnant (within marriage, of course).
"Sex is supposed to lead to babies," she said. "It's not a mistake, it's not something going wrong, it's something going right."
Bajoyo answered questions at the end of the session, and many of the participants stayed after to express support for her ideas and beliefs.
"It was particularly compelling coming from a young doctor and a female," said Monica Go, 26.
Jessica Matick, a 24-year-old nurse, said she also found Bajoyo's comments encouraging.
"It's a beautiful thing because it integrates the natural law," she said. "It's challenging and fruitful at the same time."
