The gathering's local organizer, Stan Swim, interim president of Salt Lake City's conservative Sutherland Institute think tank, welcomed foreign guests and other participants.
In addition to Mormon performers (violinist Jenny Oaks Baker and Nathan Osmond), the day's schedule offered a veritable "who's who" of Beehive State conservatives — including columnists Richard and Linda Eyre, Utah Eagle Forum President Gayle Ruzicka and United Families International founder Susan Roylance, as well as a slew of professors and staffers from LDS Church-owned Brigham Young University.
Historically, though, the Mormon connection to the congress was a tad more problematic. After all, it happened by accident and wasn't exactly welcome in all quarters.
Allan Carlson, the congress' founder and international secretary, was prompted to launch the movement in 1995 after chatting with some Russian Orthodox priests in Moscow about issues such as abortion, failing marriages, declining fertility and cohabitation.
The congress held its first international meeting in Prague in 1997, and, on the airplane rode home, Carlson was seated next to BYU law professor Richard Wilkins.
They talked all the way home, recalled Carlson, who was retiring at this meeting, and decided to form a partnership between Carlson's Howard Center for Family, Religion and Society in Rockford, Ill. and Wilkins' center at the Provo school.
The BYU lawyer, who died in 2012, became deeply involved in organizing the 1999 meeting in Geneva, persuading high-level Mormon leaders to observe, speak and participate.
The Church of Jesus Christ of Latter-day Saints was not buying into the objectives of every pro-family group present at the conference, Bruce Hafen, then of the faith's First Quorum of the Seventy, said at the time.
"There are a lot of groups here with an extensive political agenda," Hafen, now an emeritus LDS general authority. "Some of them use 'family' for issues that aren't necessarily related to the family. The church will not be aligned with the Christian right as a political action group."
The Utah-based faith was "not trying to insist on a monolithic program," he said. "The church supports a two-party system."
Wilkins, Hafen and then-Relief Society General President Mary Ellen Smoot and then-Young Women President General Margaret Nadauld all gave major speeches at the meeting.
Days before the gathering, however, Geneva's famed St. Pierre's Cathedral expressed concerns about LDS participation in its chapel, where the opening session was scheduled. Organizers assured the Swiss Reformed Church that, though Mormons were involved, the congress was sponsored by an interfaith group.
Unsatisfied, the cathedral withdrew permission to use its church, and the session shifted instead to the hotel ballroom, where the rest of the conference took place.
"It was an unfortunate decision," Carlson said at the time. "I was particularly disappointed by the lack of hospitality."
These days, it is the Mormons who are rolling out the welcome mats — including Nu Skin executive Steven Lund, a major congress donor — and promoting the faith's unique theology about forever families.
