Because marriage involved the exchange of money or a dowry, it was unclear that it should be considered a sacrament on the grounds that no one should be able to pay for divine grace. Despite these reservations, marriage was affirmed as a sacrament at the Lateran Council of the early thirteenth century. This affirmation meant that marriage was not considered as a civil contract, but a holy act. Because it is a sacrament, it is impossible to undo it, and so the Catholic Church does not allow divorce.
Annulments are possible if it can be determined that no valid marriage existed.
The Catholic Church finds evidence for the sacrament of marriage in Scriptural text. He is the saviour of his body. Therefore as the Church is subject to Christ, so also let the wives be to their husbands in all things. So also ought men to love their wives as their own bodies. He that loveth his wife, loveth himself.
