This is the Reason why the Church normally Requires that the Faithful contract Marriage according to the ecclesiastical form. Several reaSons converge to explain this requirement: 132 - Sacramental marriage is a Liturgical act. It is therefore appropriate that it should be Celebrated in the public Liturgy of the Church; - Marriage introduces one into an Ecclesial order, and creates Rights and duties in the Church between the Spouses and Towards their children; - Since marriage is a state of life in the Church, certainty about it is Necessary (hence the obligation to have Witnesses); - the public Character of the consent protects the "I do" once given and Helps the spouses Remain Faithful to it.
