RandomGuy48:

I'm a little confused by your message. Is the issue whether the marriage itself is held in the Catholic Church, or whether the groom is actually a member of the Catholic Church?

In regards to the former, to my understanding the Catholic Church does require its members to be married by a Catholic priest. But... I'm not absolutely sure about all the rules, but can't you just do both? As is my understanding, churches are free to have the religious ceremony of marriage without actually issuing a legal certificate of marriage (i.e. one recognized legally by the government), so you can just have the religious ceremony of marriage in both churches but only have one of them actually issue the legal certificate. For monetary reasons you'd presumably want one of the two ceremonies to be a simple, private affair (or maybe it's possible to have both the Catholic and Anglican priest perform the ceremony together at the same wedding--not sure though), but it seems that would be satisfactory to both of the churches in satisfying their marital requirements.

actually the Catholic Church requires her members to receive sacraments including marriage validly and licitly, which happens only in the church.
