These reasons and others led Erin Schurtz, who works at a matchmaking company for members of the church, to organize this live dating event for one of her clients. It was not her first foray into dating games: In 2010, she created a YouTube series called “The Mormon Bachelorette” with a close friend, to help the friend find a husband. The series continued after her friend got married and ran for five seasons.

“If you move away from the mecca — Salt Lake City and Provo — it makes it difficult to find someone because there are less people who are L.D.S.,” Ms. Schurtz said. But dating in Utah raises an opposite issue: “It becomes the problem of the grass is always greener; it becomes too much.”

Th ough “too much” might seem like an enviable problem, it can complicate decision-making for people who are looking to find a partner not just for life, but for ever. “We believe it’s for eternity, not just for this life,” Ms. Schurtz said. “It can cause a lot of anxiety for a lot of people. There’s a lot of early-on decision making. People will think, ‘Is this the one?’ on the second or third date.”

O.K., back to the show. Ms. Nettik found out that she was one of the 20 finalists for the “LDS Millionaire Matchmaking” event on a Monday in early June, at midnight. “I was told needed to make my meal choices and get a cocktail dress,” she said. She also signed a nondisclosure agreement, the terms of which included protecting the bachelor’s identity . (In sharing details from the event, she said, she adhered to those terms.)

At the dinner, Ms. Nettik bonded with the other attendees, many of whom she said were around her age — quite a bit younger than the bachelor, who the matchmaking company said is between 35 and 45 years old. During the event, he hid behind a white sheet while people who knew him described his accomplishments. After the sheet came down, Ms. Nettik said, the bachelor presented a PowerPoint outlining his reasons for being there. (She would not share details .)
