An Episcopal rector who not only holds a top position in the Pittsburgh diocese but is also a vocal advocate for Bishop Robert W. Duncan Jr. has been placed on administrative leave for three months for "inappropriate language" with a parishioner.

The Rev. David Wilson, rector of St. Paul's Church in Kittanning, Armstrong County, was placed on leave Saturday. During the three-month leave he will not serve either as church rector or in his position as president of the diocese's standing committee, which advises the bishop.

"The diocese upholds a very high standard of behavior for its ministers," diocesan spokesman Peter Frank said. "While the behavior involved inappropriate language, it technically falls within a policy that demands zero tolerance."

Mr. Frank declined to provide details.

In an e-mail response to a question, Father Wilson wrote: "I fully accept the godly judgment of my bishop, Robert Duncan." He declined further comment.

The Rev. Carl Neely, who is retired, has been appointed priest-in-charge of St. Paul's until May 31.
