This story, from the Curt Jester, sets it out straight. I don't usually put such a sizeable exerpt up, but I'll make an exception here because I think it's important. It's also important for you to read the whole story, and check out the Curt Jester on a regular basis while you're at it.
This is what then Cardinal Ratzinger actually wrote as head of the CDF in response to questions posed.
...Members of the faithful who live together as husband and wife with persons other than their legitimate spouses may not receive Holy Communion. Should they judge it possible to do so, pastors and confessors, given the gravity of the matter and the spiritual good of these persons(10) as well as the common good of the Church, have the serious duty to admonish them that such a judgment of conscience openly contradicts the Church's teaching(11). Pastors in their teaching must also remind the faithful entrusted to their care of this doctrine.
This does not mean that the Church does not take to heart the situation of these faithful, who moreover are not excluded from ecclesial communion. She is concerned to accompany them pastorally and invite them to share in the life of the Church in the measure that is compatible with the dispositions of divine law, from which the Church has no power to dispense(12). On the other hand, it is necessary to instruct these faithful so that they do not think their participation in the life of the Church is reduced exclusively to the question of the reception of the Eucharist. The faithful are to be helped to deepen their understanding of the value of sharing in the sacrifice of Christ in the Mass, of spiritual communion(13), of prayer, of meditation on the Word of God, and of works of charity and justice(14).
7. The mistaken conviction of a divorced and remarried person that he may receive Holy Communion normally presupposes that personal conscience is considered in the final analysis to be able, on the basis of one's own convictions(15), to come to a decision about the existence or absence of a previous marriage and the value of the new union. However, such a position is inadmissable(16). Marriage, in fact, because it is both the image of the spousal relationship between Christ and his Church as well as the fundamental core and an important factor in the life of civil society, is essentially a public reality.
8. It is certainly true that a judgment about one's own dispositions for the reception of Holy Communion must be made by a properly formed moral conscience. But it is equally true that the consent that is the foundation of marriage is not simply a private decision since it creates a specifically ecclesial and social situation for the spouses, both individually and as a couple. Thus the judgment of conscience of one's own marital situation does not regard only the immediate relationship between man and God, as if one could prescind from the Church's mediation, that also includes canonical laws binding in conscience. Not to recognise this essential aspect would mean in fact to deny that marriage is a reality of the Church, that is to say, a sacrament.
Hmmm, the dangers of the secular press talking about what it doesn't understand...
