Etsuko Stanhope is a missionary to Mormons, so we can't show you her face - seriously.

This Sydney Anglican is the motivating force behind a new website witnessing to members of the Church of Jesus Christ of Latter-day Saints in Sydney.

"My job is to place a stick of dynamite next to a Mormon's heart and wait for the Holy Spirit to ignite it," she says, borrowing a line from an American preacher.

But Ms Stanhope says becoming recognisable as an evangelist would put Mormons on edge, and she is keen to remove whatever barriers she can for the gospel.

"When we argue with Mormons about their beliefs or the dubious character of Joseph Smith their shutters come down," she says.

"Instead, we need to allow the power of the gospel to go to work."

That is the philosophy behind the Mormon Outreach Ministries website which strives to inform Mormons about the claims of Jesus in a familiar manner, rather than debate their core beliefs.

"Mormons have a unique way of communicating," says Ms Stanhope. "And the classic presentation of the gospel may not convey what we intend."

"Like missionaries to Papua New Guinea or anywhere else, we need to understand their culture and speak their language," she explains.

Ms Stanhope completed her theological education at Mary Andrews College as well as Morling College, where she focused on "Alternative Religious Movements'.

Her passion for Mormons drove her to contact various churches looking to support whatever outreach was going on.

When she discovered there was no Mormon-specific ministry, she linked in with the members of St Paul's, Carlingford and other like-minded people to establish MOM.

Nearby St Paul's is Australia's largest Mormon temple, which includes training facilities for visiting Mormon missionaries.

The MOM website, launched in 2003, is still in its infancy but currently draws around a hundred new visitors every month, with the majority coming from Australia and the United States.

It allows Mormons to investigate the claims of mainstream Christianity without fear of exposure.

"Mormons and potential Mormon converts will visit a website privately rather than discuss the issues in person," Ms Stanhope says.

"We hope it will equip many Christians to defend their own faith and to share the gospel effectively with Mormons from their own cultural context."

People interested in promoting or supporting the Mormon Outreach Ministry can contact Ms Stanhope through the MOM website.
