This is actually quite simple to deal with. It’s essentially a three-step process. But first, we need to clarify some terms.
“Excommunication” is a specific term. It’s often times thrown around rather loosely. But, rest assured, marrying outside of the Church Is NOT excommunicable. What was probably said is that you should “refrain from receiving Communion until this situation is rectified,” or something along those lines. “Excommunication” is not the same as “not being able to receive the sacraments.”
When someone says “have your marriage blessed,” what he or she means is to have what’s known as a convalidation. They’re quite common. I do them all the time. We’ll get there in a minute.
Ok…here are the steps.
- Your wife needs to get her first marriage annulled. The only way she can do this is to go to a Catholic Church and speak with someone. This will probably be a priest, but could be a deacon or even a lay person, depending on the parish. This process could be rather easy, or could be more involved. The only way you’ll know is to speak with someone.
After step one is done, your wife will be free to enter into marriage with you. Right now, the Church assumes her first marriage is her valid (read “real”) marriage. Until that is proven otherwise through the annulment process, she is not free to enter into marriage in the Catholic Church.
- Step two is to go through the marriage preparation process at your local parish. Different parishes and dioceses will have different requirements for the two of you. Speak with your local priest or deacon.
- Third and finally, you will be married in the Catholic Church. Again, the technical term for this is “convalidation.” Most people colloquially say “have your marriage blessed.”
Until then, follow the wise advice of others and refrain from sexual relations, as you are not married to this woman. I’ve been using the word “wife” for the sake of simplicity. But, in truth, she’s not your wife. If the two of you abstain from sex, and live “as brother and sister,” there is no reason you could not receive the sacraments. I know and have worked with many couples in this exact boat who live a vibrant sacramental life while things are getting sorted out.
