The following isn't a statement by a leader of the LDS Church, but it might be useful in understanding why this is said. It is from a 2001 Newsweek article. The entire article may be read at the link.
For example: with Olympic fever heating up, the church's hierarchy recently advised the media that the term Mormon Church is no longer acceptable. Henceforth, officials declared, short references to the church should read: "The Church of Jesus Christ." In this way the church hopes to emphasize what Mormons share with historic Christianity, not what makes them different.
Internally, this emphasis on Jesus has been even more dramatic. Traditionally, Mormon teaching focused on founder Joseph Smith as God's latter-day prophet whose revelations led to the restoration of the ancient Hebraic priesthood and of the one true church. Today more than one image of Smith is hard to find in the church's magnificent new conference center in Salt Lake City. Instead, the walls are lined with huge murals depicting scenes from the life of Jesus. This change in iconography can also be seen in local chapels, called "wards," where Mormons gather every Sunday for three hours. In 1971, images of Jesus appeared only five times in the church's official monthly publication, the Ensign; in 1999, the Ensign published 119 of them. For nearly a decade, visitors to the Joseph Smith Center in Salt Lake were shown "Legacy," a film about Smith and the grueling Mormon trek to Utah. Today there is a new film, "The Testimonies of One Fold and One Shepherd," a Disneyesque dramatization of the Jesus story based on both the New Testament and the Book of Mormon.
More important,
Mormon rhetoric is becoming more overtly evangelical. In the sermons by the church's General Authorities and in the language of their prayers, the stress on grace and forgiveness of sins and on Jesus as atoning savior of the world sounds almost Methodist or even Southern Baptist. Are the Mormons going mainstream? "Not at all," says non-Mormon historian Jan Shipps, who has studied the Saints for 40 years. "After a century of cultivating their separate identity as a religious people, Mormons now want to stress their affinities with traditional Christianity yet highlight their uniqueness." Or as President Hinckley declared to Mike Wallace in a 1996 interview on "60 Minutes," "We are not weird."
