Ben Seewald kept mum when news broke out earlier this year that his brother-in-law Josh Duggar had molested five underage girls, including his own sister and Ben's wife Jessa, when he was just a teenager.

He maintained his silence when it came to light that Josh had two paid accounts on the hacked extramarital dating website Ashley Madison and admitted being unfaithful to his wife Anna.

But Ben's father Michael isn't going to let the scandal pass by without saying something.

"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," he wrote in the Seewald's website entitled "Grief, Shame, and Taking the Lord's Name in Vain."

"It distresses me to say that Josh Duggar's greatest sin is a by-product of the sum total of his secretly sinful lifestyle. That is, that by his hypocrisy, he blasphemed the name of God," Michael further wrote. "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."

What Michael considers extremely hurtful is that Josh, being a member of the Family Research Council, used to endorse Christian ethics. Now that has been exposed as a fraud, Josh has brought "shame on God's holy name and the Christian faith," Michael Seewald said.

When he first heard about Josh's child molestation raps, Michael said he and many other individuals came to Josh's defense, thinking and saying that he was already a changed man. But in the end, Michael said Josh simply "deceived us all."

"To the person reading this, I want to caution you. Josh was a pretender," Michael 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."
