After some observations, relevant to the matters of the Christian wedding, submitted to the attention of the Bishops in the preparatory task to the Council Vatican I, the abstract pauses to analyze the issue of the civil wedding, thematic that was analysed in that occasion with particular attention to the theoretical and practical consequences that an acknowledgment of the juridical status of the civil wedding, would have implied in the canon law. Closely connected to the problematic deriving from the civil wedding, it turned out the demand, promoted by several parties, to grant more wide faculties to the Bishops for dispensation from the impediments of ecclesiastical law. In particular the need to exempt from the religious obligations had to do with the impediment of “mixta religio” as settled by the legislative decree of Tametsi and by the “Declaration Benedectina” of Benedict XIV, the impediment of consanguinity and affinity, that one of public honestas, and finally the impediments of cognatio legalis and spirituals. The conclusions try to highlight the position of the Church on the civil wedding: from the attitude of total closing held during the Council Vatican I to the new attitude deriving from Vatican II where that was Acknowledged in the code of 1983.
