Cardinal Burke: Divorced And Remarried Can Receive Communion If They Firmly Resolve To Live Chastely....
“In the whole history of the Church, it’s never been possible that someone who was living publicly in a state of sin, for example a person who is bound in matrimony to one person, is living in a marital way with another person, it has never been permitted that such a person could approach to receive Holy Communion,” Cardinal Burke
But if the couple makes a promise to live 'chastely' ...then its OK:
“The Church has always helped such couples,” he said, “… the point is this: that the couple has the firm resolve to live chastely, and to take all measures to live chastely. If they fail, on one occasion or another, then they simply have to confess that, and renew their effort to live chastely.” Cardinal Burke
