One of our diocesan transitional deacons, who, by the way, is a convert of mine (there are three seminarians in our diocese who are converts of mine from St. Joseph's in Macon, but I digress) recently told me that he did a radical sanation. I was shocked, because I have never done one and only vaguely remember being told about this quirk of canon law. Although I am certain I have heard about it but at 66 I can't remember when.
What is so radical about it, is that when a couple enters a civil marriage not recognized by the Church because of impediments, the Church presumes this marriage is invalid and thus the couple is "technically" living in sin, an adulterous relationship.
Then the couple seeks to have their civil union blessed or "convalidated" in the Church, meaning an annulment is sought for any previous marriages or impediments are removed by the Church.
Once the annulments are granted or impediments removed, and the couple is in a stable, conjugal relationship which they intend to honor for life, baptize and rear their children Catholic, their marriage is retroactively recognized and blessed from the moment of their illicit weddding ceremony.
How's that for being radical. What I have indicated is that there is no need for for a Catholic ceremony to validate the Marriage. That's radical folks.
Did you know this?
