Robertson's comments came during Wednesday's episode of "The 700 Club," ABC News reported.
A woman named Ivy wrote to Robertson for advice, saying, "We have gone to counseling, but I just can't seem to forgive, nor can I trust. How do you let go of the anger? How do you trust again?"
In response, Robertson said: "Stop talking about the cheating. He cheated on you. Well, he's a man. O.K."
"Males have a tendency to wander a little bit, and what you want to do is make the home so wonderful that he doesn't want to wander," he said.
Robertson's comments provoked criticism from women and other Christian leaders.
"I think it's outrageous. Historically, Christians take personal responsibilities for our actions and immoral choices and don't blame those on other people," said Gabe Lyons, author of "The Next Christians."
The Christian Broadcasting Network defended Robertson in a statement, saying, "As a first step in the process, Dr. Robertson stated that she should stop dwelling on the cheating. Next, he recommended that she remind herself of all the reasons she fell in love with him in the first place so that she might try to fall back in love with him all over again."
"Lastly, his point was that everyone is human and there is much temptation outside of the home, so she should do whatever she can to strengthen their home and relationship. His intent was not to condone infidelity or to cast blame. We regret any misunderstanding," the statement concluded.
