The marriage rule is simply one I personally do not agree with. I am not going to go to confession for having a civil wedding ceremony because 1) I am not sorry for making that choice and 2) I remain married and therefore confession/absolution is meaningless in this instance and 3) nowhere in the Bible does it state that a marriage is only valid it is takes place in a church, by a priest and it that priest agrees that the marriage is a good idea and agrees to marry you.
And you are not simply willing to go to the rectory and get the marriage convalidated, quietly?
This is a rule man up by our church leaders that I think needs to be re-evaluated.
Can. 227 The lay Christian faithful have the right to have recognized that freedom which all citizens have in the affairs of the earthly city. When using that same freedom, however, they are to take care that their actions are imbued with the spirit of the gospel and
are to heed the doctrine set forth by the magisterium of the Church. In matters of opinion, moreover, they are to avoid setting forth their own opinion as the doctrine of the Church.
Can. 750 §1. A person must believe with divine and Catholic faith all those things contained in the word of God, written or handed on, that is, in the one deposit of faith entrusted to the Church, and at the same time proposed as divinely revealed either by the solemn magisterium of the Church or by its ordinary and universal magisterium which is manifested by the common adherence of the Christian faithful under the leadership of the sacred magisterium; therefore all are bound to avoid any doctrines whatsoever contrary to them.
§2. Each and every thing which is proposed definitively by the magisterium of the Church concerning the doctrine of faith and morals, that is, each and every thing which is required to safeguard reverently and to expound faithfully the same deposit of faith, is also to be firm-ly embraced and retained; therefore, one who rejects those propositions which are to be held definitively is opposed to the doctrine of the Catholic Church.
Can. 752 Although not an assent of faith, a religious submission of the intellect and will must be given to a doctrine which the Supreme Pontiff or the college of bishops declares concerning faith or morals when they exercise the authentic magisterium, even if they do not intend to proclaim it by definitive act; therefore, the Christian faithful are to take care to avoid those things which do not agree with it.
At least you can’t claim invincible ignorance…
