Jessa Seewald’s father-in-law posted a blog slamming Josh Duggar.

Michael Seewald said in his blog that the 27-year-old’s secret extramarital sex life is an example of taking the lord’s name in vain.

Michael Seewald is the father of Ben Seewald, who married Josh’s younger sister Jessa Seewald last November.

Jessa’s brother admitted that he cheated on his wife, Anna Duggar, using the Ashley Madison website. Anna’s brother Daniel Keller then posted on Facebook last week that he “won’t stop trying to get that pig out of our family.”

And now, Jessa’s father-in-law expressed his disdain for Josh Duggar, calling him a pretender and hypocrite.

Michael said that while Christians commit sin, Josh’s actions were so much worse because he pretended to be of upstanding moral fiber.

“While proudly saying things like, ‘our family is like the epitome of conservative values,’ he was looking at porn and soliciting affairs. He took a job at the Family Research Council that exists to promote the traditional family, all the while undermining his own family by violating his marriage covenant,” Michael Seewald said in his blog post.

“He flourished in the fame of his family and the success of their television show, all the while betraying their trust and Christian values,” Michael added.

Jessa Seewald’s father-in-law said he felt deceived. He said he stood by Josh last May, but after Josh admitted he molested five girls, including his sisters, his second scandal shows that Duggar still had an extensive lifestyle of evil.

“Sadly, he had deceived us all,” Michael writes. “The name of God has been blasphemed and God is jealous for his name.”

Jessa Seewald’s father-in-law said that what’s hurtful in Josh Duggar’s admission is he was a loud voice endorsing Christian ethics and he has been shown to be a fraud.

Josh Duggar had checked into Reformers Unanimous in Rockford, a rehab facility in Illinois offering a treatment based solely on the Bible according to People.

Meanwhile, Jessa Seewald and her husband Ben didn’t comment on the issue and instead shared details about their first months of marriage, and their preparation for the new member of Duggar-Seewald family.
