I am aware of the present marriage preparation course conducted in various dioceses. it is done well and is useful.
I would like to know, in which century did the church start preparing her faithful for marriage? are there any historical background, apart from familiaris consortis. was any kind of preparation happening prior to JP II 's time?
or marriage preparation is just a recent phenomenon?
AFAIK, it is a fairly recent phenomenon to address the problem where pre-nuptial couples do not have enough knowledge about Christian marriage. However, the idea was as old as time memorial because for every Sacrament we have to know what it entails. Thus before a priest performs the rite of Matrimony, he has to explain what it is to the intending couple first.
Even the phrase, ‘till death do we part’, holds a self explanatory meaning but a young couple in love eager to get married may probably do not appreciate in depth what that has in store for them.
The pre-nuptial marriage seminar is really a move of the Holy Spirit this century. Sometimes at the end of the sixties, some Catholics who were involved realized the needs for the deepening and actualizing of the Christian faith in their lives. It is not just something you are born with or a necessary resume to our names, but one that should be actively lived and believed.
Basically that has to start from the family which has its origin in a marriage.
Marriage is not just about marriage between husband and wife, which it is of course, but it encompasses equally important responsibility like bringing up children and not rejecting the idea of having them.
Of course we all are supposed to know this but then again how much do we know? The pre-nuptial seminar covers the important aspect of Christian marriage requirement and when properly appreciated it would make a great deal of difference to the couple’s marriage life.
Thus where this was first experienced, and where the married couples show fruits and became active in their parishes, and started to introduce the seminar to other couples, eventually its benefit was well recognized to become the standard norm for a couple intending to get married.
