I can only indicate what the law of the Church says on a given matter, and seek to do that accurately. I have no desire to convince but only to state things correctly and believe I have. Individuals may agree or disagree with the substance of the law, but they should at least know what it is.
Canon 1108 provides: “§1. Only those marriages are valid which are contracted in the presence of the local ordinary or the pastor or a priest or deacon delegated by either of them, who assist, and in the presence of two witnesses, according to the rules expressed in the following canons, with due regard for the exceptions mentioned in cann. 144, 1112, §1, 1116 and 1127, §§ 1 and 2.”
Canon 1157 says, “The renewal of consent must be a new act of the will concerning a marriage which the person who is renewing consent knows or thinks was null from the beginning.”
I cautioned the original poster Kayla to consider this latter point during her catechesis and formation for the sacrament. My comment was in that context and directed toward her clarification. My use of the citation by a prior poster was to illustrate the concept correctly. Perhaps in retrospect, I might have stated the correction by merely restating or paraphrasing the substance of the post more generally. Applying the law to his individual situation as to draw any conclusion about what God thinks of his individual situation is not my prerogative nor intention, nor would it be the purpose for which Church law exists. But my statement of the law itself is correct. The law is what it is.
Two broad questions have been raised in this discussion: 1) how one accepts the authority of the Church to regulate the sacraments, and 2) the role of individual conscience. The second opens up an even broader issue.
We should be at least clear that the Church asserts this authority in canon 841, that since the sacraments pertain to the divine deposit, it belongs to the supreme authority of the Church alone to approve or define the requirements for their validity. The sacraments of the New Testament were instituted by Christ the Lord and entrusted to the Church (canon 840). So at least, we must state the law of the Church in regard to the external forum, what can be publicly observed and regulated.
The second broad issue is that individuals do apply or fail to apply the law to their own circumstances through the exercise of conscience. This conscience may be informed or uninformed, correct or erroneous. Error may be vincible or invincible. A judgment regarding conscience is not the realm of law, since law regulates the external forum.
In the practical order, what a person did or did not do, thought or did not think, at a wedding ceremony, original or convalidation, will have consequence if a marriage is investigated for validity in a tribunal. Otherwise, the question will not really be asked.
In the moral order, and in the final analysis, conscience and human actions are accountable to divine and not judicial judgment. Ultimately a term like “validity” is a judicial category. The good faith in which parties approach convalidation, clearly intending to do what is right and seek the “blessing of the Church,” is a moral category.
In my opinion, a person who is troubled about the matter though in his or her own situation and in a existing marriage which he or she wishes to continue might benefit from the counsel of a priest in the internal forum.
