When a person joins the Church (through RCIA) do they have to have their marriage validated? What if their spouse isn’t Catholic, and doesn’t want to join the Church? If they get a divorce, do they have to get an annulment, if they weren’t married in the Church?
Welcome to CAF!!!
When I converted to the Catholic Church in 2003, my then wife (my second wife) would have nothing to do with it; she hated Christians and Christianity.
I had been married previously so I needed to get that marriage addressed and I received an annulment. Next, I needed to get my current marriage convalidated in the Church.
My understanding of how convalidations are done is fairly limited. However, I believe that normally the couple attends a Mass, any Mass, and after the homily the Priest calls them forward and they take the wedding vows. Then Mass then proceeds normally. I saw this happen only once after a couple had just been confirmed.
In my case, my wife absolutely refused to take part. I was told I could not receive communion until my current marriage had been dealt with. I knew that my wife was going to divorce me soon as she was demanding that I cease going to Church. In this case, I applied for what is called a “radical sanation” which effectively says that since we had previously made civil vows (well, not quite civil, we were married by a Wiccan witch and high priestess, though we were both atheists at the time.) and I now desired a sacramental marriage that our marriage was sacramentally valid.
A few months later, my then wife fled the country and divorced me from overseas. (I receved a declaration of nullity last year so I am free to marry.)
So yes, you do need to have marriages convalidated or made sacramental in some manner in order to receive Holy Communion. The basis for this is that the Church recognizes that there are two types of marriages, civil and sacramental. In order for married persons to receive Holy Communion, their marriage must be sacramental. (A marriage can be presumed to be valid even if it is not sacramental, something that confuses many people.)
At least, that is my understanding. If I am wrong in some detail, I invite those who are better informed to correct me.
