I have seen mixed viewpoints ranging from "need a Bishop" to "it's up to both of you how you raise your family" . I live in Moscow and have plans to have a civil ceremony later this year with my Russian fiancée. She wants a church wedding here later this year in Ireland. Can a non-practicing Russian Orthodox lady marry a semi-practising Roman Catholic man in an Irish Catholic Church?

Only practicing Catholics who don't have an impediment to the marriage - such as an undissolved prior Catholic marriage - can be married in Catholic ceremonies.

I know that half of the question!
