Let us accept that as fact that the guard did draw a cross in the sand. Let us also accept that McCain was a practicing Christian while in prison. It is very reasonable to believe that as most when found in those condidtions he found faith. So accepting that he while imprisoned was a devout Christian the ultimate question becomes did he keep the faith once freedom was found and the threat of meeting his maker not a daily thought.
I must assume that a marriage vow made in the eyes of God between Man and Woman is one of the basic tenets of Christianity. I believe the good senator said such Saturday at the Saddlebrook Forum. Was his affair and divorce a result of Christian relapse which he has now regained? Was he not a Christian when he first married? Does anyone have documentation of when he first professed his faith? Was it before or after the vows of his first wedding. Had he not made such broad claims of faith in prison one would not wonder about the disconnect after prison. Yes he now says it was a moral failure but he did not elaborate on the conditions of and the sequence of in relation to his prison story. So should one ponder how sincere and deep morally deep his prison faith was? In reality was it no different then the many who find faith while incarcerated?
