My DH is Greek Orthodox and I am Catholic, we had a GO wedding (I had a disspensation from the Catholic Church) and our Daughters are both Christened GO, that being said both will hopefully attend the local RC school, DH has had more Catholic schooling than me, they won't be attending the GO schools as the one closest is very very biased "GO is the only way to go" whilst the RC schools are more open around here.
