The Code of Canon Law of 1983 classifies the reasons for marriage invalidity in three different categories: diriment impediments, defects in matrimonial consent and lack or defect of canon form. Among different defects in matrimonial consent, in its can. 1101 § 2, the Code of Canon Law enumerates simulations. Simulation signifies that a person contracting marriage expresses marital agreement merely on the surface, excluding in reality, through a positive act of will, the marriage itself, some essential elements of or an essential property of marriage. The grounds for excluding the sacramental dignity constitute a novum as compared to the Code of Canon Law of 1917. The present article attempts to look at the relation between the lack of faith and the exclusion of marriage sacramental dignity, with the consideration of marriage invalidity.
