Catholic2003:
No, living as brother and sister is unrelated to use of the internal forum.
I disagree with you.
Under the papacy of Pope Paul VI, the Sacred Congregation for the Doctrine of the Faith’s document of April 11, 1973, which addressed the Diocesan Bishops and censured the admittance of invalidly married persons to the sacraments, stated in the final paragraph:
“With regard to admission to the sacraments, the local ordinaries will also please, on the one hand, stress the observance of the current discipline of the church while, on the other hand, take care that
pastors of souls follow up with particular solicitude those who are living in an irregular union and, in addition to other correct means, use the approved practice of the Church in the internal forum.”“Judicial jurisdiction is expressed by the word *Forum…
The internal forum is subdivided into the sacramental or penitential, which is exercised in the tribunal of penance or at least is connected with it, and the extra penitential forum… Thus the absolution of sins belongs to the internal forum” *(Catholic Encyclopedia - Ecclesiastical Forum).
The lawful pastors of the Church have judicial jurisdiction of the external
and internal forum. The internal forum is exercised by either the
tribunal of penance, or excercised via extra-penitential pastoral communications with the lawful pastor. We are bound to obey the pastor as the legitamite judicial authority in the internal forum, so long as his direction is within the scope of his authority (i.e., not contrary to HIS lawful pastor).
Not any “internal forum solution” will due. It is to be the “approved practice of the Church.” So, what is the approved “internal forum” practice?
On March 21, 1975, the same
Sacred Congregation explained the phrase “the approved practice of the Church in the internal forum” in the following way:
"The couples may be allowed to receive the sacraments on** two conditions**, that they try to live according to the demands of
Christian moral principles and that they receive the sacraments in churches in which they are not known so that they
will not create any scandal."Now, if you have not been granted an annulment, then you are still married to another. To live in accord with
Christian moral principles has a very specific meaning, and it doesn’t include having sexual relations with someone who is not your lawful spouse. A civil divorce has no authority in ecclesiastical law. You are still married to the other spouse unless the ecclesiastical authorities, in the external forum, judge that your prior marriage was null (never sacramentally valid to begin with).
Are you saying that only those couples who are morally certain that their first marriage is invalid, even though they cannot prove this in the external forum, can choose to return to communion by living as brother and sister?
No. Even if they re-married (illicitly, I might add), but later come to realize that their first marriage was still valid, they are obliged to separate and return to their first spouse. For serious reasons, return to the first spouse may not be obligated (e.g., abuse, unfaithfulness).
Or, they can, for “serious reasons” (eg. upbringing of children), remain in the irregular marriage so long as they meet the conditions of the Church-APPROVED internal forum, that is 1) abstain from conjugal relations, 2) receive sacramental absolution and 3) avoid public scandal.
