Frank Houston established Sydney Christian Life Centre in 1977, which later merged with Hills Christian Life Centre, founded by Brian, to become Hillsong.
The church surged in popularity in the United States and around the world, attracting celebrities and young people with music and a style of preaching that emphasized positivity.
The ideal Hillsong sermon “leaves people feeling better about themselves than they came,” Mr. Houston said in his guidelines for church leaders in Australia.
That approach — known as “seeker sensitive” — has earned Hillsong a large following in urban areas like New York, where stars such as Justin Bieber, Selena Gomez and Kevin Durant have gathered at popular concert venues to participate in its Sunday services.
But scandal is not new to the church.
Last November, Mr. Houston fired Carl Lentz, the head pastor of the New York branch, for “leadership issues and breaches of trust, plus a recent revelation of moral failures,” as Mr. Houston wrote in an email to churchgoers. Mr. Lentz later confessed on Instagram that he had been unfaithful in his marriage.
Mr. Houston, who is usually based in Sydney, was granted a rare coronavirus travel exemption to leave Australia this year. He has recently conducted services in Mexico and is believed to be currently residing in the United States with his wife.
