That still doesn't make sense. They had no problem saying that their ordained ministers can baptize, marry, etc. Most of them still have a form of communion. So, it seems that they still could have retained it, as Lutherans have (I won't even try to get into Lutherans' belief of Consubstantiation vs. Catholic/Orthodox Transubstantiation, because it confuses me).
The ministers can marry through the authority of the state, not the church. And anyone can baptize; Catholics agree. Their communion did not involve a consecration, but only a sharing in (I'm series) Pepperidge Farm goldfish and grape juice by the congregation.
They don't believe that Jesus did anything to the bread and wine at the Last Supper, other than offer a blessing as anyone could. Therefore, they can "commemorate" that occasion simply through the sharing of the congregation, no minister needed.
As I said, I don't agree, of course, but it seems internally consistent to me, except for the goldfish (which my friend mentioned because she thought it was appalling!).
