LITHONIA, Ga. — Eddie Long, the flamboyant megachurch pastor whose reputation was tarnished after former congregants accused him of sexual misconduct, has died. He was 63.

Rev. Long died Sunday after battling cancer, New Birth Missionary Baptist Church in Lithonia said in a statement.

Senior pastor at New Birth Missionary Baptist since 1987, Rev. Long oversaw the church’s explosive growth, with membership swelling from a modest 300 to 25,000.

The church operated television and international ministries and built satellite churches in several cities, including Miami and Denver.

Rev. Long was also an author and a gospel singer. He was known for preaching and practicing a ‘‘prosperity gospel,’’ in which the faithful would be rewarded with wealth.

He was also known for his flamboyant lifestyle, as he flew around the world on a private jet, drove around metro Atlanta in a $350,000 Bentley, and lived in a $1.4 million house with six bedrooms and nine bathrooms.

In 2006, the church hosted then-President George W. Bush and former presidents Bill Clinton, Jimmy Carter, and George H.W. Bush during the funeral of Coretta Scott King, the widow of Martin Luther King Jr.

‘‘As I reflect on his life, I am especially remembering Bishop Long’s support during some of the most difficult times in my life. the passing of my mother in 2006, and the sudden and unexpected loss of my sister in 2007,’’ King’s daughter, Bernice King, said in a statement.

Scandal erupted in 2010, when four young men filed lawsuits accusing him of sexual misconduct. Rev. Long’s lavish lifestyle was a focal point in the suits, which accused him of seducing the young men into sexual relationships in exchange for trips, clothes, and cars.

Two of the men had accused Rev. Long of grooming them for sexual relationships through the church’s LongFellows Youth Academy.

Eight months later, Rev. Long settled the cases out of court for an undisclosed amount and has never admitted any wrongdoing. Some congregation members changed their opinion of him, but many others rallied around the charismatic leader.
