"The right of the Church has always established–said Monsignor Laffitte in a particularly significant interview–that no marriage between two baptized persons is possible unless it is sacramental. This means that a baptized person can legitimately ask the Church for the sacrament. However, it is contradictory to ask for a sacrament and to not care about what the sacrament is or, even more simply, about being baptized. In this kind of case, the situation requires pastors to consider both the way in which they give the sacrament and the preparation of engaged couples. Does the fact of not having faith invalidate the sacrament that is given? The answer is 'no': in itself, the lack of faith does not eliminate the fact that the only marriage possible between two baptized persons is a sacrament. On the other hand, one of the grounds for the revocation of a sacramental marriage is the failure to adhere to the so-called 'essential properties of marriage' (unity, indissolubility)."
