According to the Catholic Church, the seven sacraments of Baptism, Eucharist, Confirmation, Anointing of the Sick, Reconciliation (Penance), Matrimony, and Holy Orders are considered the outward showing of salvation and inner grace. Only if the sacrament was not lawful from the moment it was conferred, can it be renounced. The Catholic Church has created the annulment process that declares a sacrament invalid from the very beginning. An annulment is referred to as a Declaration of Nullity.
The Catholic Church holds that a married couple cannot divorce for any reason whatsoever. However, marriage annulments are granted for a variety of reasons by the Catholic Church. Some of these reasons are a lack of due discretion, defective consent, psychological incapacity and a defect of form (that includes marriages performed by a non-Catholic minister or weddings held outside of a Catholic Church).
Although Jesus taught that divorce was only written into the law because of human stubbornness (Matthew 19:8) and that the original intent of God was for the spouses to never separate (Genesis 2:24), He permitted divorce in cases of sexual immorality and marital unfaithfulness (Matthew 5:32).
The annulment process is not found in the Bible. Jesus only allowed divorce for sexual immorality while the Catholic annulment allows dissolving the marriage for several other reasons, but not for sexual immorality.
