With Josh Duggar in Rehab, Wife Anna Joins '19 Kids and Counting' Family for Sermon Message On 'Sin of Pornography'

Anna Duggar, the wife of embattled former reality star Josh Duggar, attended a Sunday church service with fellow "19 Kids and Counting" stars Jill Duggar and Derick Dillard that focused on the sin of pornography.

According to the Daily Mail, Anna attended Cross Church with her four children and her in-laws, including Jim Bob and Michelle Duggar, to hear a message from Pastor Jeff Crawford focusing on sexual sin.

"Pornography is a secret sin," said Crawford during the service. "I know there are some folks in here today - pornography is a deal in your life."

The message was particularly timely for the Duggar family, as Josh recently entered rehab for "long-term treatment" after admitting to cheating on his wife and struggling with pornography.

The admission came after a hacking group known as the "Impact Team" last month revealed Josh paid nearly $1,000 for two subscriptions to Ashley Madison, a website used to facilitate adulterous relationships.

At the time, Josh, who married Anna in 2008, wrote: "I have been the biggest hypocrite ever. While espousing faith and family values, I have secretly over the last several years been viewing pornography on the internet and this became a secret addiction and I became unfaithful to my wife."

The father-of-four continued, "I am so ashamed of the double life that I have been living and am grieved for the hurt, pain and disgrace my sin has caused my wife and family, and most of all Jesus and all those who profess faith in Him."

He added, "I brought hurt and a reproach to my family, close friends and the fans of our show with my actions that happened when I was 14-15 years old, and now I have re-broken their trust."

Josh, 27,  previously served as executive director of the Family Research Council, a conservative lobbying group in Washington D.C. that seeks "to champion marriage and family as the foundation of civilization, the seedbed of virtue, and the wellspring of society."

However, he resigned in May after reports surfaced that he molested two of his sisters and another girl when he was a teenager. The revelations also brought an end to his family's hit TLC show, "19 Kids and Counting."

While Josh's family supported him throughout the molestation scandal, they have expressed genuine shock and horror over his affair and addiction to porn.

"We are so thankful for the outpouring of love, care and prayers for our family during this most difficult situation with Josh," Jim Bob and Michelle Duggar wrote in a statement. "As parents we are so deeply grieved by our son's decisions and actions. His wrong choices have deeply hurt his precious wife and children and have negatively affected so many others. He has also brought great insult to the values and faith we hold dear. For him it will be a long journey toward wholeness and recovery."

Last week, Josh's sister, Jessa Seewald, tweeted out a link to a blog penned by father-in-law Michael Seewald that suggested her brother might not be a Christian.

The blog titled "Grief, Shame and Taking the Lord's Name in Vain" addressed the Ashley Madison scandal which outed several other Christians as users of the site.

"What is troubling is that many who take the name of Christ are among its members," wrote Seewald.

"It distresses me to say that Josh Duggar's greatest sin is a byproduct of the sum total of his secretly sinful lifestyle. That is, by his hypocrisy, he blasphemed the name of God. He claimed to be a Christian, but by his deeds he has suggested otherwise. With the name of God on his lips he lived a covert and extensive lifestyle," added Seewald.
