Bishop Lopes, Ordinary of the Ordinariate of the Chair of S Peter in North America, has issued a very fine instruction on the question of the "remarried" divorced.
In this document, printed in its entirety in the National Catholic Register, he binds together formulae from our Anglican (Patrimony) Marriage Service; from the Catechism of the Catholic Church (which Benedict XVI's Anglicanorum coetibus formally declared to be the official doctrinal statement of the Ordinariates); from S John Paul's Familiaris consortio; and from Amoris laetitia. Drawing sensitively upon our corporate experience when we were still separated from the Unity of the See of S Peter, he shows how the whole Biblical doctrine of the use of sexuality handed down by Tradition unravels, with increasing rapidity and violence, once an ecclesial body starts 'making exceptions' which the Incarnate Word Himself explicitly excluded.
Bishop Stephen's Letter demonstrates exactly how immensely valuable it is for the Catholic Church to have a separated tradition such as ours, with its own liturgical inheritance, its own centuries-old experience of the Christian life, entering, enriching, and strengthening the Tradition which is from the Apostles. It is, surely, for fine teaching such as this that God called us into unity.
As it happens, our liturgical inheritance in this matter is not in its origins Protestant at all. Of all the Sacramental rites in our Prayer Book tradition, the service of Holy Matrimony is the one which Archbishop Thomas Cranmer messed around with least. This is because, despite Henry ("It was null just like the last time!") Tudor, the Church of England substantially preserved Catholic Truth in the matter of the indissolubility of Marriage. Accordingly, much of the traditional Anglican Marriage service stays word for word in line with that of the Medieval Catholic Sarum Manuale (i.e Rituale). There, of course, much of the Wedding Service had to be in English ... so that bride and groom understood to what they were assenting. And perhaps also because the congregations knew the words so well.
After the Reformation, English Recusant Catholics continued to use Sarum, so that for centuries Catholics and Anglicans in England got married with (almost) the same words; words already sanctified by centuries of use.
Cranmer's main change was to introduce a text for the priest to read at the beginning of the Service ... which was very orthodox!
