I carefully wrote "divorced and re-married". In Catholic doctrine, a person who is divorced from a valid marriage and re-marries, is living in perptetual mortal sin, which even confession can't remove. Only separation from the second marriage, or death of the first spouse AND CONFESSION, can remove the sin. Therefore, they can't be saved while they remain in that condition. (if they die with ONE mortal sin unconfessed)
They also have no sanctifying grace from God. The Holy Ghost does not make His aboad in a soul in mortal sin. That is why I said "I know they have not God's grace".
