"They remain steadfast and resolute about working through this together," the source says, "and they have every intention of reclaiming their dignity and their name."
The last time Camille issued a statement was in December 2014, after a slew of allegations by women that her husband drugged and/or sexually assaulted them.
"The man I met, and fell in love with, and whom I continue to love, is the man you all knew through his work," Camille Cosby said in the statement.

Cosby's lead attorney, Monique Pressley, called the charge "unjustified" and says they will mount a vigorous defense. He has also denied drugging and/or sexually assaulting the more than 50 other women who have accused him.
On Wednesday, Camille, 71, is scheduled to be deposed in a defamation lawsuit filed against her husband by seven of his accusers. Cosby has countersued them as well.
Late Monday, Magistrate Judge David Hennessy ordered the deposition, if and when it does happen, be kept under seal.
Joseph Cammarata, the attorney who subpoenaed Camille, says he fully intends to proceed as planned Wednesday "absent a court order" directing her not to appear.
