Personally I would say yes as ANYONE is allowed to take communion as long as the understand what it means. I dont know whether Catholics would agree with this though.

I need to say FIRST, I am NOT an authority on ANY religion, let alone the Catholic one, HOWEVER, I was Catholic at one time in my life and that one time just happened to be when I got married. I was Catholic and my husband-to-be was not. Having recently converted to Catholicism, I knew that we had to attend marriage classes and that we had to have the blessings of the priest/church to marry. I went to the Priest and asked him about marrying us and was told NO, not without my future spouse taking the marriage classes with me. Unfortunately, whether my future spouse was willing or not, the classes were being held AFTER the date we had chosen for the wedding so the point really was moot. My future spouse was in the military and was being sent overseas and we wanted to marry before he left. Because of this I asked for special dispensation and a special meeting for the 3 of us. Needless to say, that didn't happen because the priest didn't feel it was a good thing for us to marry before my future spouse left. He felt we should wait until he returned and could enroll in the NEXT marriage classes. Since this was really out of the question, I asked if we could get married in a different church, one of his faith, and was told that if I did, my marriage, and any subsequent children from the marriage, would not be recogoized by the Catholic church and the children would be considered illegitimate. I am NOT making this up. This is what I was told by the priest to my face...not from a go-between or word of mouth (bad advice). I questioned this answer as I was going to be married by an ordained minister, in a HOUSE of GOD and therefore did not see how God wasn't going to recognize the union or the children of that union. Nevertheless, this is what I was told. I informed the Priest that I was going to do it anyway because I felt that God would accept and honor it no matter what he was saying to me. I was then given one more "warning" and that was that if I followed through on my plans to marry outside of the Catholic church and without their (again, the Cathlic church) blessing, then I would never (I repeat - NEVER) be able to receive the Eucharist (Communion) during mass. I was welcome to continue to attend mass, but I couldn't receive Christ. Why would anyone go to church if they weren't "allowed" to receive Christ? Isn't that the whole reason for going to church? To worship Christ? It was at this point that I chose to leave the Catholic church and have publicly renounced my Catholic beliefs. So, having said all of that as a basis for knowing what I'm talking about (because it happened to me) then the answer to your question is NO...a Catholic can NOT receive communion if they are married outside of the church to a non catholic UNLESS the couple went to the marriage classes beforehand and their marriage was sanctioned/approved by the Catholic church...HOWEVER, again, technically, the Catholic church ALSO doesn't recognize the marriage of a practicing Catholic that is held in ANY place other than a Catholic church. If a priest authorizes it (and make no mistake, the Priest is the one who gives or denies permission) to take place outside of a Catholic church then he too, is breaking the "rules" as Vatican II is the last time the rules were changed for the Catholic church and my "event" occured 15 years AFTER Vatican II so that means the rules that applied to me more than 25 years ago, still apply today. But again, I have to reiterate...I am NOT and AUTHORITY on the subject. I simply know what happened to me in this EXACT same situation. I can only assume the same rules would still apply since they haven't been changed in all this time.

I was a non-Catholic marrying a Catholic in 1989, however that fits into Vatican II as described by sammy326, who gave a remarkable description of her experience, I think. My fiancee and I took the pre-cana classes to get permission to marry, and I did not convert. We were married by the parish priest, Father Tony - a fine man, and commenced to ignore church for a long time. Since we did the classes and married in the church, our situation doesn't match exactly with the original question, but I'm posting this because your situation might change and resemble my experience. The wife was not prohibited from communion, however, at that time. After our divorce, granted without annulment, she remarried to a Catholic but outside the church and is again inactive, although her new husband is active and takes communion regularly. I hope this doesn't get him busted because he's a pretty nice guy.

Yes, of course! It is possible to receive a dispensation from the church to marry outside the church and to a non-Catholic. For example, if a Catholic wanted to marry a Jewish person in a synagogue it would be ok as long as they get the dispensation first. A Catholic can marry outside the church to a non-Catholic without the dispensation BUT the marriage would not be recognized by the church which means the person is living in sin and thus, the Catholic would not be a state of Grace and could not receive communion. However, you can still get the marriage blessed after the fact (as long as the normal conditions that apply for an R.C. marriage apply) and the Catholic can make their confession and again receive communion.
