Frank Sinatra famously sang, “Love and marriage / love and marriage / they go together / like a horse and carriage” – and while that may be true, just like a horse and carriage, there is always a hitch! And the hitch that connects love and marriage, like the hitch of the horse and carriage, has to fit together in such a way that the two are properly bound together. When marital hitch can’t properly connect to the carriage of marriage, we call that an “impediment.” A marital impediment is something that impedes the marital union from happening. Sometimes that marital hitch can’t be fixed; other times the local Bishop is needed to help you fix that hitch; and still other times you have to send your hitch out to the repair shop in the Vatican for fixing.
The Church, as expressed in its Canon Law, teaches that there are 12 impediments to a Sacrament of Marriage; these are commonly called Diriment Impediments. Diriment is a word that comes from the Latin dirimens, which means separating. Thus a Diriment impediment is one that separates the couple (or better put, it causes them to be unable to be joined). Of these impediments, three are based on Divine Law. They come from God; if these impediments are present, they are not dispensable, even by the Pope. Another three are deemed as “reserved”; this means they can only be dispensed by the Pope (the Holy See). The remaining six are dispensable by Church authority in the person of the Bishop.
Some impediments are more impeding than others to marriage – and just as for many years TV had the “big three” networks: CBS, NBC and ABC – the Church has the big three non-dispensable impediments, to wit: impotence, prior marriage and consanguinity. Each of these impediments emanate from Divine Law (i.e., God said so).
The next three impediments to marriage are deemed “reserved,” this means they can be dispensed but only by the Pope. They are:
The remaining six diriment impediments are all dispensable by the Bishop. I would be remiss if I failed to note that while the Bishop can dispense from some of these impediments it doesn’t mean that he likely would.
Also note that prior to 1983 in the Roman Catholic Church (and currently still existing in the Eastern Church) there was a 13th impediment: Spiritual Relationship. This impediment dictated that a marriage between a Godparent and a Godchild – even if not connected by blood, affinity or adoption – is not permissible.
There are, of course, other matters that impede marriage or render it potentially invalid: coercion (forcing someone to marry); refusing procreation (when one party in a marriage makes it known that he/she doesn’t want to have children); lack of form (when a Catholic gets married without following the marital laws and rites of the Church); exclusion of fidelity (if either party says that he/she can’t be faithful); and mental incapacity (if either party doesn’t understand what he/she is entering into).
