Catholic AnswerMarriage. There is no such thing as "blessing" a civil or other religious marriage, you are either married in the eyes of the Church or you are not. If you are not, then you must get married, it is a real marriage ceremony. We have these all the time when a Catholic has been married outside the Church and the non-Catholic spouse goes through RCIA and converts, then they are married in the Church. "Blessing" is just a nice non-judgmental word to explain what you are doing to your protestant relatives who think you are already married.
