I have written about this before and have recently re-posted my original article on Josephite Marriages. Almost monthly, I am meeting couples who have chosen this way of holiness, as I noted in the first article I wrote two years ago.
Some saintly couples already noted on this blog chose Josephite Marriages, and I mentioned a fictional couple in my novella, who chose such a lifestyle.
As times become more perilous, couples may consider this path of holiness. Most of the couples I know who have chosen this path are just beyond child-bearing age. In other words, they made the decision to be completely chaste. As they had given God children, as expected from good Catholics, and as one of the huge reasons for marital relations no longer was possible, these couples prayed and spoke with spiritual directors about their decision.
The couples prayed first, of course, and came to the decision together, first.
As is most obvious, a Josephite Marriage is named after St. Joseph, who did not have marital relations with the Blessed Virgin Mary. This marriage was completely celibate, and some Josephite marriages are so.
There is a confusion among some modern people on the validity of a Josephite, or non-consummated marriages, unlike the ones described above. If a couple is married in the Church and has been living together for a length of time, the marriage is assumed consummated. A Josephite Marriage is called ratum tantum in Canon Law. Note, that when a couple are married in the Nuptial Mass, or with the Nuptial Blessing, they are "married". In the Church today, a non-consummated marriage must still be the subject of an annulment if a party decides to leave the marriage, divorce, and re-marry.
One may reference this post and others under the tag, "marriage" on this blog for more information.
