The Oxford Movement restored in practice much of the "catholicity" that had been stripped out during the reformation. It's a long story that few here would find interesting. Suffice to say that the Oxford Movement was the genesis of "high church" or "Anglo-Catholic" Anglicanism. It was embraced more in some provinces than others. It was highly influential in the U.S. particularly in the northern states, not so much in the south, and had a profound influence on the 1928 Book of Common Prayer of the Episcopal Church - which was replaced in 1979 but is still the standard for worship in the continuing Anglican churches in the US.
It is interesting to note that the Oxford Movement is what led to asking Rome for an opinion on Anglican orders, to which Rome declared them "absolutely null and utterly void." How ironic that a return to catholic practice led to the formal rejection whereas all during the years of protestant practice Rome remained officialy undeclared in re Anglican orders.
