The in-laws are not happy with Josh Duggar.

In a blog post, post titled "Grief, Shame, and Taking the Lord's Name in Vain," Michael Seewald, the father of Josh's brother-in-law Ben Seewald, bashed the former lobbyist, calling both a "pretender" and a "hypocrite" when it comes to representing his Christian faith.

"In commenting on this I do not wish to add any more distress to a family still recovering from the indignity of the publication of a police report detailing Josh's sins as a teenager," Seewald wrote in a blog post Monday.

"Though I have never gotten to know Josh very well, I have great respect for his sorrowing parents and immense sympathy for his dear wife Anna and their four children. I myself have been mourning over the irreparable damage that has been done to many by this whole circumstance, yet the reason I feel obliged to make these remarks is an overwhelming desire to vindicate the name of God." 

Seewald addressed Duggar's lifestyle from a biblical stance, saying that the reality star misrepresented and degraded "the name of God," saying that, "God is holy and he cares how his name is handled."

In August, the former "19 Kids and Counting" star was the first celebrity named in the Ashley Madison hacking scandal after the website was targeted by a secretive group called "the Impact Team."

Gawker reported that Duggar had had two accounts on the cheating website and paid close to $1,000 for extramarital affairs. As previously reported by HNGN, Duggar created his Ashley Madison account in 2013 and named "Conventional Sex," Experimenting with Sex Toys," One-Night Stands" and "Open to Experimentation" as his sexual desires.

Seewald admitted that he wasn't surprise to learn that over 30 million people signed up for Ashley Madison, a website designed to help married men and women find their next affair; however, what was troubling to him was "that many who take the name of Christ are among its members."

"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, that by his hypocrisy, he blasphemed the name of God," Seewald continued in his post. "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 of evil."

Seewald went on to bash Duggar's false image of a perfect family and later added, "The thing that is so hurtful is that he was a loud voice endorsing Christian ethics and he has been shown to be a fraud. I am profoundly grieved that he attained such a platform only to bring shame on God's holy name and the Christian faith."

While Seewald was quick to defend Duggar following his child molestation scandal - where the disgraced reality star admitted to molesting five underage girls as a teenager - Seewald argued that this time Duggar simply "deceived us all."

"To the person reading this, I want to caution you. Josh was a pretender," he wrote. "True Christians fail often, but their lives are truly being conformed to the image of Christ. Do not look at Josh and justify your own sins by dismissing the reality of genuine faith and a holy God. When you stand before God, you will not be compared to hypocritical Christians. You will be judged by God's holy law."

Duggar has apologized directly to his family for his embarrassing scandals and has checked "himself into a long-term treatment center" following his confession to cheating on wife Anna Duggar, who has reportedly also been receiving counseling. Last week, Anna's older brother, Daniel Keller admitted that he was not happy with his sister's decision to remain commented to her husband, following his admission, according to People. 

"I have told her I would pay for her to move out here w[ith] me and pay for her kids," Keller wrote on his Facebook. "I don't think Josh will see that this is a big deal and truly be broken until that happens. I [bet] my life on the fact that Josh has not come to true brokenness yet."
