If you go by Catholicism they will say the marriage is not valid. My mother in law married through the Episcopal Church, after more than 18 years of marriage and following a new faith, she became Catholic, the priest told her she had to get married again by the Catholic Church because basically she had been living with her "partner" during all those years without being married by the catholic church, and she did get married again.
Other christian faith? IDK what they say exactly about it. But most protestant churches do believe marriage is an institution created by God.
