The Seventh-day Adventist Church has convened a special committee to examine allegations of improper business transactions by its president, Robert S. Folkenberg, according to officials of the church, whose headquarters is in Silver Spring. The committee of 20 church members, some of whom are flying in from other countries, will begin meeting Monday at the Dulles International Airport Marriott Hotel to review the allegations. Church officials yesterday declined to provide details of the questionable transactions, which came to light after a former business partner of Folkenberg, James E. Moore, of Sacramento, sued him and the church last year. The lawsuit alleged that Folkenberg and others had violated the terms of a business agreement with Moore. "I am not able to discuss {the allegations}," said the committee's chairman, Niels-Erik Andreasen, president of Andrews University, a church-affiliated seminary in Michigan. He said the allegations against Folkenberg "did involve business transactions to some degree, but it is not clear if they involved church funds." Folkenberg, who lives in Fulton and was elected president of the church in 1990, could not be reached for comment. His attorney, Joe Reeder, said Folkenberg had requested next week's meeting. "The lawsuit is frivolous, and {Folkenberg has} asked to be able to talk to church folks about that" at an "informal, informational" meeting. Talking to the other church leaders is "exactly what Elder Folkenberg wanted," Reeder said. Moore's allegations "are untrue," Reeder said. "Elder Folkenberg knows the allegations to be untrue. We know the allegations to be untrue. The church leaders who've studied them know them to be untrue." According to an internal church document, the "Special Ad Hoc Group" will spend two days reviewing church-related issues pertaining to the allegations. If the committee, which includes both laity and clergy of the 10 million-member church, determines that the allegations warrant further action, it will make recommendations Wednesday to the church's top governing body. Church spokesman Ray Dabrowski said the ad hoc group, which has been set up by the administrative committee of the Seventh-day general conference, "is going to address or look at certain aspects that have transpired in the wake of the lawsuit in California." Moore's allegations, he added, concern activities by Folkenberg "that the plaintiff alleged may have compromised his position" in the church. Moore's lawsuit, filed in August, named Folkenberg and Walter Carson, another top church official, as well as the church itself among the defendants. He said they reneged on a 1993 business deal involving the swapping of shares in companies. After the lawsuit was filed, attorneys for the church learned about other allegedly improper business transactions by Folkenberg, according to a church source. It is these newer allegations, "outside of the lawsuit," that are the focus of the committee's review, spokesman Dabrowski said. On Jan. 12, the church issued a statement to its leadership saying that the claims against the church in Moore's lawsuit were "frivolous and without merit." The statement said Moore was "a business entrepreneur . . . who was convicted of felony grand theft in 1989 and who served time in prison." Reached yesterday at his Sacramento office, Moore declined to comment. "I'm going to not comment on anything," he said, including whether he had served time in prison.
