The Southern California church headed by popular evangelical Pastor Rick Warren says his 27-year-old son has committed suicide.

Warren's Saddleback Valley Community Church announced that Matthew Warren had struggled with mental illness and deep depression throughout his life.

Warren, whose church numbers nearly 20,000 members, also supports more than 200 community ministries and groups for parents, families, children, couples, prisoners, addicts and people living with HIV, depression and other illnesses.

Warren, author of the best-selling book "A Purpose Driven Life," also gave the invocation at President Barack Obama's inauguration in 2009.
